raditya Report post Posted January 25, 2015 Hei.. I'm radit from Indonesia.. I'm new to leatherworking..and i want to know what thread size for making a slim wallet.. I've already make one..but I think the thread size doesn't fits well ( my seller says 1,2mm in diameter), especially when doing the finish stitching (top left corner of the wallet) So..i need sugestion on that thread size..you can see from the attachment photo.. I really appreciate any suggestion.. Quote Share this post Link to post Share on other sites
Matt T Report post Posted January 25, 2015 (edited) Depends on how you want it to look. I would go for around 0.5mm on a wallet though. Edited January 25, 2015 by Matt T Quote Share this post Link to post Share on other sites
raditya Report post Posted January 25, 2015 Thanks Matt.. Is 0.5mm strong enough..?? I want to make it clean and neat actually..but with the stitching result like that I think I need to change the thread size.. Quote Share this post Link to post Share on other sites

Matt T Report post Posted January 25, 2015 If you are using polyester or nylon thread the leather will probably rip before the stitches if you pull hard.

Matt T Report post Posted January 25, 2015 With ramie or hemp, it will probably break before the leather; but that's usually what you would want. You want your thread to rip just before the leather would give away; that way you can repair the item. The sizing is a little complex.
