Ugly Stitches

[Trox]

With one layer leather and a big needle this will happen. The needle punches the material down and you will have these puncture marks, thats normal. A smooth hammering of the backside will take care of it. With lined leather you will avoid it. Its also harder to conceal the thread knot in the middle with heavy thread, size it down and use a leather needle (LR or other point). You can of course try more thread tension, then again an upholstery class machine do not have as much tension as big stitcher has. Use a needle that cuts instead of punching like a LR and you will have a much better result.

I also am curious about needle and thread size if anyone else has any info regarding what size needle to use with what size thread. Also what size thread for what thickness of leather too
