Contributing Member SooperJake Posted June 21, 2012 Contributing Member Report Posted June 21, 2012 I am working on my fourth leather project/ holster and I am wondering what I am doing to cause some of my stitches to look zig-zag, while the others look nice and linear. I sewed the reinforcement on first, then sewed the left side, then the right. I was trying to put the needle through on the same side of the other thread every time, and not pull too tight, which I note crinkles up the leather. Back to front then front to back, following the Stohlman book on hand sewing. The right side looks awesome. I don't see anything covering this in the book. Help, please!

Members markush Posted June 21, 2012 Members Report Posted June 21, 2012 (edited) Others will be along to give you more insightfull info I'm sure, but I might suggest going to more SPI (stitches per inch). I'm taking a guess in saying it looks like your doing something like 4 1/2-5 SPI. A higher SPI should smooth out the appearance, especially on tighter radiuses. I've always liked the look of 6 SPI myself. I'm curious why your leather is crinkling if you pull the stitches tight....are you sewing wet leather? Edited June 21, 2012 by markush Quote
Contributing Member Ferg Posted June 21, 2012 Contributing Member Report Posted June 21, 2012 I believe your holes are too large. What type of thread are you using? ferg Others will be along to give you more insightfull info I'm sure, but I might suggest going to more SPI (stitches per inch).

Members katsass Posted June 21, 2012 Members Report Posted June 21, 2012 FWIW from the grump: Both of these guys are right IMO. Ferg has been at it a long time and Markush does some pretty good stitching. Holes are too big --- If you can pull the needle through the hole with your fingers, they're "too damned big" --- that is exactly what I was told (and taught) over 50 years ago, and I still use a small pair of smooth jawed pliers to stitch with. If not using harness needles (I generally use a #1 size, but no larger than a #0) you may be splitting the first strand through. And, about 6 SPI is a good, all around stitch size. It almost looks as though you are using synthetic sinew for thread --- tain't that good an idea for holsters, again, IMO. I have always used waxed linen threads. Nyltex is also a good thread. Remember, always start each stitch from the same side of your project, then go either over, or under, that one with your second needle, BUT, ALWAYS do each succeeding stitch in EXACTLY the same way, either over, or under, but don't mix them..

Contributing Member SooperJake Posted June 21, 2012 Author Contributing Member Report Posted June 21, 2012 Actually, it may be a combination of all three of the above answers, gentlemen. I'm using the Craftool 4 mm stitching punches, and the spikes on the 2 prong are thicker than the spikes on the 4 prong, by a third at least, increasing the diagonal impression. That, and I think I pried the 4 prong out to the side rather than straight out, in some cases. I know, it is cheating. I bought the punches after my first holster, because the stitching looked so bad. At first I thought it was a clockwise, anticlockwise thing. So, I did a test strip last night which didn't reveal anything, other than that wasn't the problem. But, after thinking real hard about what I did, and staring at a closeup of my photos, I remembered my four prong punch was missing for a time ( left in shirt pocket in laundry the day before) , so I had used the 2 prong to punch the reinforcement piece, and then used it on account of the curvature on the left side. Carefully punched holes in scrap reveal a significant difference in hole size between the two. The thread is a waxed nylon from Tandy (Professional saddle stitching thread coated with pure beeswax. 25 lb. breaking point. 25 yard spool ), and I couldn't tell you what size that is, or what size the needles are that I bought. Thanks for your help! Jake Quote Once you know what the magician know.... it isn't magic anymore.

Markush, Crinkling (to me) is the bumpy texture I see running parallel to the stitching. It seems more pronounced when I pull the threads Sooper tight. Picture a Gorilla in a glass shop and you'll get an image of me sewing. My manual dexterity isn't what can be classified as 'graceful' . I am, however, shooting for consistency, be it the stitch sequence or the tension pulled. It seems logical that the tpi has an effect on this too, pinching less leather over a shorter span ? If I understand correctly. The items I am using where suggested by the clerk at Tandy, for the most part, and he admittedly didn't make holsters. Dry leather.

Thanks for your help! Jake From the grump --- again: First off I despise those 'stitching' punches. Pick up a decent (narrow) diamond (shaped) awl to poke holes with, and a #6 overstitch wheel to mark and --- go over your stitches when done (hence the name --over-stitch) then practice a bit with both. Second (maybe first) IMO Tandy was pretty good --- 40 or more years ago. Today they are more suited for the Cub Scout group activity stuff --- again IMO. I generally tell anyone starting out making holsters to get Al Stohlman's book "How to Make Holsters", it's well worth the $12 or so, and most all makers I know have their copy --- and even refer to it now and then. If purchased from Tandy, your needles are most likely 00 or even 000 in size -- too damned big --- again IMO. I have nothing to do with Springfield Leather except for being a satisfied customer, but you might call them (they advertise on this forum and have an 800 number) and get their catalog -- it has a pot-load of informational tidbits mixed in the pages. You can talk with the very knowledgeable folks about awls, needles etc.and get straight info from them, and see what a very good leathercraft dealer has to offer.

Mike Mike, your wisdom is noted, very well. I am not enamored with Tandy, already. I did practice with a small bladed awl, then did my first holster, which didn't come out too good. I thought the punches would clean things up a bit, giving me some consistency. I do have 3 Stohlman books, including holsters and hand stitching, which I was referencing while I worked. Of course, the awl came from Tandy, too, and I spent a couple hours sharpening it, which weakened the blade since so much material had to be removed to get a decent edge on all 4 planes. I bent the tip, which spurred me on to get the punches. Calling Springfield's now. Thanks, Jake Quote Once you know what the magician know.... it isn't magic anymore.

Thanks, Jake Well, with the risk of being labeled a heretic, one thing that I have done to assist someone in learning to use the awl is to allow the use of a Dremel type tool -- with a 3/64" bit. Nothing larger than that.You can carefully drill them, and then set your piece in a stitching pony (or not) and open each with the awl -- just a bit. As you go, you'll learn how to hold the thing and about how much pressure is needed. If you mark the spacing with your overstitch, drill out a dozen or so, open them up a little --- pretty soon you'll be able to just keep going without stopping to drill more holes. It may take a while before the use of the awl becomes normal and easy, but remember this --- stitches CAN be pulled through the leather with pliers and not being opened up with the awl. To many this is just a terrible idea, but I think you'll find a hell of a lot more 'closet drillers' than will admit to it in public. Just a suggestion.

mlapaglia Posted June 21, 2012 Report Posted June 21, 2012 (edited) Blasphemy!!!!!! But a darn good idea. Are you using the eazy thread needles from Tandy? They have the Eye you could drive a camel through? Get a #0 harness needle to start. You over sharpened the awl. Get the small one only. Then only sharpen the front 1/4 to 1/2 inch. You want it to spread the wider part of the hole so it closes. If you cut the entire hole it doesn't close as well. Also if you haven't tried it yet put a cork behind the leather and push through into the cork with the awl. It saves fingers and makes it easier.
