Dear Francis,

a big big thanks for posting those pictures here, just found them. They are another stone in the mosaic I'm slowly putting together to better understand how these shoes were made in their detail. I just found another interesting article from a few years ago on this shoe: http://www.museum-digital.de/nat/index. ... oges=29398
The article itself (in German) is in:
Waffen- und Kostümkunde 2/2002:
Irmgard Sedler, Wilfried Schreier, Gerlinde Koch. Schuhtechnik in Barock und Rokoko. Zur historischen Schuhsammlung im Museum Weißenfels

It shows a different construction method it seems to me around the white rand in that there is none of the fine stitching along the lower edge of the rand but coarser stitching on the upper edge of it, done so that it more or less disappears in the fold between the upper and the rand.

Cheers,
Martin

G'day Every-one,
Hopefully this is an interesting, multi part, post :)
This isn't about work at 64spi, but it is about prize work and trying to understand a little more about the methods.
Since recently seeing the photos of the 1800’s, prize work, black and green boots, I’ve been spending a lot of time staring at it, trying to figure out how the beautiful, diagonal, lay of the stitches was achieved. This is beyond the normal, subtle, lay that is produced with hand sewing, and though I didn’t achieve the same results, my sewing has benefited from the experiments.

The boots in question.

One of the possibilities that came to mind was that, instead of making the holes vertical in relation to each other (my usual practice) viz. IIIIIIIII going from the bottom of one hole to the top of the next (All of these are stitching from left to right), maybe the shoemaker was canting the holes forward viz. ////////, so that the stitches, on the visible side of the work, would have to travel further, from the bottom of the first hole to the top of the next. Another possibility (though counter intuitive in my mind) was that they were canted backwards viz. \\\\\\\.
I was also wondering if he used larger holes and thread than I would have normally assumed, for the frequency of stitches, to accentuate the diagonal.

Pt 2

I decided to give it a try by sewing a test piece, changing my methods about every ten stitches and recording, on the back, what I did.
pic 4 copy.JPG
The reference to ‘knot’ is when you wrap one thread once around the other on it’s way through to the other side. It helps force the stitch into a diagonal. The method that turned out the neatest and most consistent was the second from the left; the holes tilting away from the stitches so that the thread has to travel a longer distance, and no ‘knot’.

The following pic. is the front, so you’ll have to reverse the order of the sections shown in pic. 4. The best section is the 10 stitches in the middle of the photo underlined in red. I repeated this stitch method after my last variation, to finish off the test seam, and check it wasn’t a fluke :) (underlined in blue).
pic 5 copy.JPG
The sections with the ‘knot’ in them tended to mush together, especially the section between the red and the blue lines.


Afterwards I tried 11 stitches at around 50% increase in stitch length, in case I was too short, but it didn’t come out as nice and was harder to be consistent. I suppose the most important thing with hand sewing is to work with your own natural rhythm. The prize worker that started this investigation has a beautiful rhythm, and technique, that suits him. I tend towards ‘squarer’ stitches, though will continue to think about the mechanics of producing different stitch lay effects.

Pt3

For those who are interested, here’s how I produced the prime sections.

The awl doesn’t travel very far through the leather (kangaroo hide); the point is coming through just above the free end of the thread.
pic 6 copy.JPG
I’m using the tiny bristles that I showed in the ‘Thread rolling’ Vimeo clip ( ). One bristle per end of the thread, and they completely pass each other and swap sides.
pic 7 copy.JPG
Instead of pulling the threads straight through the leather (how I did the very first section, far left in pic.5), I pull the left hand thread forward, to keep it tracking in the far top of the hole, and the right hand thread I pull backwards to keep it tracking in the near bottom of the hole.

Here you can see that the thread loop, that is traveling over to the left side of the work, is forced to go over and past the right hand thread.
pic 9 copy.JPG
Around 19 spi (stitches per inch)
pic 10 copy.JPG
And for the metrics, a bit over 1mm per stitch.

Hope this has been interesting.

Duncan,

Looks like you're onto it :thumb:

Only thing I might add, historically, that fine stabbing was done with a round awl, so no ///// or \\\\\\\ shaped holes. And as I offered at HCC AGM this year, odd-stranded threads stay round, even-stranded threads lay flat. Making the "half cast" (knot) gives that rope-y effect, as does insuring you always insert your bristles exactly in the same order/same one to the front at every stitch. Any deviation here results in a stitch out of alignment.

Great work Duncan! 1mm stitches comes out to about 24spi by my calculations.

Al,

I have always thought...from talking to you, perhaps...that in order to do really high frequency work--50+spi--the unstitched leather would have to be forced up against the previous stitch perhaps with a bone or the side of the awl itself. This is a fairly common technique at other junctures and would maximize the substance in each stitch and help to prevent the awl.

I also wonder..and have asked but don't remember any answer I might have received...what the thread would have been. It seems to me that a single strand of even #20 linen yarn would be a little too coarse and fragile. Where as silk thread--so much more appropriate for high end work anyway--would have been the better choice.

G'day DW,
The 40yrold, single ply, linen I use takes several pounds pull to break, and if you think about it, every stitch has two 3lb threads going through it, one from each side, making each stitch about 6lb breaking strain, times by the number of stitches (lets say 50spi) which equals an inch having a collective breaking strain of 300lb! The 48spi, single strand, seam I did, and tested some years ago, sewing together two 1/4mm thick pieces of veg. 'roo, only failed when the bottom vice slipped off (under 14kg/30.8lb strain) resulting in it pulling down on one end of the sewing, zip style, tearing the leather (not the thread) for about 1/3 of the stitches. So 14kg focused on a 0.5mm stitch ( to start the chain reaction) would equal how much force? As a comparison: It was calculated that the tiny area under a ladies stiletto heel, being the focal point of the wearer's weight, exerted around 1 or 2 tons of pressure, hence they had been known to punch holes in aeroplane floors etc.

So, in the end, the quality of the leather is, I think, more important than the thread, so that it can cope with the frequency of the stitches. Within limits, a higher stitch count with hand sewing will increase the strength of the seam as the collective breaking strain of the stitches goes up, and there is more support from the leather.
eg: Two identical set-ups for a seam 1 inch long.
One has 5 stitches joining the pieces; the other has 25 stitches.
Apply an increasing pulling force to them both.
The 5 stitch seam will have all the force focused on those 5 stitches and they, if the thread is strong enough, will act like cutters through the leather.
The other seam will have the force distributed over the 25 stitches, dividing the force by 5, therefore enabling it to take 5 times the load.
This is why I use Veg. Kangaroo :)
Sound good to you? :)
Cheers
Duncan

Oh, don't worry Al, identical alignment of the bristles has been the norm since I learnt hand sewing in the '90's. Putting the half cast in these fine stitches, as I commented, seemed to 'mush' them together and make each one less distinct (as opposed to using a heavy welt thread), so the neatest variations were 'half castless' :) The thread I used in this was a 3ply, but will have to give the round awl a try for some really fine work. I have made a couple of fine round awls and have used them for regular sewing, and for where a row of stitching crosses over another row.
:)
Cheers

Duncan,

Didn't mean to insult--your hand-stitching is very nice. For super-fine, try clamping a tiny sewing needle in a pin-vice for a stabbing awl.

My comment was typed with a smile on my face, Al :) That's the problem with typing, lacks subtlety even with emoticons.
I do have a pin vice in my collection. Hadn't thought about using one of those to try out a selection of different needles quickly to find the one that suits the stitch the best. Thanks. I tried one of my fine 'point' awls yesterday after your post. I need more practice before it's as neat as my regular awl. The crease line to sew on, for a start, has to be *much* finer than usual so that the super fine tip drops into the same line each time.
Cheers
Duncan

Thanks Steve and Martin. Yeah, give it go if you can get a hold of good enough linen thread. A long fibre, single ply, 'Z' twist thread is difficult to get. My stuff is over 40yrs old, and I met up today with a flax spinner with a view to getting her to hand spin fine 'line' flax (3 foot long fibres) for me to try out. We'll see how that goes.
Cheers
Duncan

Duncan:

I've thought about trying to find someone to spin flax for me as well. It is easy enough to get the long fibers from various sellers. I've also tried to locate someone to sell hemp fibers, which I guess can be as much as 10 feet long (and which don't rot), but don't think I ever succeeded in that search. In the USA, growing hemp has been illegal for decades, due to confusion with marijuana. Now, some states are allowing its cultivation, so perhaps the long fibers will become available.

Let us know how that goes!

Hi all,

I want to say thanks to all the contributors on this topic. I didn't knew it was "possible" to sew so small. It is very interesting.
I have made some tests about sewing size, thread and awl. My finest test was 19 dpi using a thread number 1032 (the finest I have found) http://travail-du-cuir.fr/astuces/adequ ... -t980.html. I think I will try to go further now I read this topic ;-)

Damien,

Great to see your efforts at achieving this. I think the antique 64/" stitching was done with silk thread. But more than finding thread to do it, I would think, is finding a leather today that would hold-up to that many stitches per inch.

das,

I always thought so too...not so much because I have any great historical knowledge but simply because linen is so coarse.

That said, some of the same problems as with linen or hemp applies to silk as well--there is long "staple" silk and, what do they call it? "tow"? I have some commercially spun silk thread ( I think it's Rice) in three or four colours for use in a sewing machine. It is disappointingly weak. Pick it apart and the fibers are short...maybe an inch at best.

Well, the lady who I met with the other day looked at the single ply thread I use as the basis and said 'That's very thick'. I suppose if you pulled apart the antique 'Shoemaker linen single shoe' thread I've got, it would have at least 50 fibres in it at any one point. This lady talks about spinning 'line flax' at 2 or 3 fibres! and commented that it's very strong for it's thickness; the fibres in line flax are around 30" long. This stuff might be saved for fine upper sewing :)
Looking forward to the end results over the coming months.
Cheers

Not exactly 64, but this little wheel does about 38 to the inch, which is more than I can see without magnification. Looks like it's seen business. Do they come much finer than this?

The other interesting thing about this little stitch wheel is the bent shaft. Where the bent shaft joins the rest of the tool (effectively the handle), the joint allows the shaft to rotate. As a result, it doesn't matter how you hold it, the tool automatically "self levels" and can only be used this way up (it turns over if you try and use it the other way up). This self-levelling also removes any slack in the wheel so it goes exactly where you want it to and is very accurate. It came from France (in a batch of tools on ebay). A brilliant design.

Though production techniques vary from country to country, from hormone-fed, "fast growth" feed-lot cattle in the USA, which produce the biggest and loosest hides, to "free-range" or grass-grazing cattle in Europe of moderate tightness and density, all the way to East India "kips" and (water) buffalo calf from Asia and India.
It seems I'm a little late on this topic @das and @dw, but I was wondering if you have heard of some recent agricultural developments. It's recently come to my attention in my day job that there are (relatively) new grazing techniques that have been pioneered in Africa and have been gaining some ground in the USA, under the banner of "holistic management" aka "intensive rotational" and "planned grazing". I believe there is quite some evidence now supporting this method, despite naysayers aligned with the status quo, and the claims that done properly it can regenerate desertifying pastures (and incidentally sequester large amounts of carbon). A few years ago I went to a conference in London on this, and was impressed by the ranchers I met who had put their livelihoods at stake by investing in this new approach. They all swore by it.
Anyway the relevant to this is that the cattle don't lounge around in feedlots or even on pastures, they are continuously rotated, to mimic the action that predators would have exerted on wild herds of ruminants in prehistoric times. They stay on a ley 1-2 days max, sometimes being moved after a few hours depending on conditions. Also given the need to move so often barbed wire fencing tends not to be used, as electric fencing is much easier and faster to move around. There are also benefits for animal health, and in this method the breed of cattle used tend to be smaller as such animals are apparently more suited to the continuous movement required.
I guess that all of this should on the face of it produce denser-fibred hides with less damage from pests and barbed wire. I'm not sure why you noted "poorer pasture" as a plus point in the post I quoted from @das - the pasture from this method should be more abundant and higher quality. I wonder if the skins of the original wild Bison in the US were less dense for grazing the lush pastures of the unspoilt prairies?
I note recently that the fashion brand Timberland have just marketed a "regenerative agriculture" boot, using hides exclusively from holistically managed herds: https://www.timberland.co.uk/shop/en/tbl-uk/eal. This has been done in conjunction with the "Savory Institute" that train farmers in holistic management and certify resulting products.
Unfortunately nobody at Savory knows anything about the qualities of the resulting leather, or whether the entire hide was processed separately or (as I suspect) the soling type leather went into the general supply chain. Nor does information seem to be forthcoming from Timberland. All I got on inquiry was empty management speak about working with "brand partners" and "enhanced brand value". But somebody must know! Anyway, just thought I would put this out there, in case anyone has heard what the leather is like or would be interested / in a position to find out more.
