Hi, I'm trying to use box stitch to create a 3D shape around a curve. Does anyone have a recommended way to to mark stitching holes on both pieces of leather? If I mark them with the same spacing, the holes on the outer piece can not catch up with the holes on the inner piece because of the thickness.
I'm also worried that if I only mark the holes on the outside and stitch with an awl, the holes that come out on the inside will be too close together.
Please let me know if you have a good way to solve this! Thanks!
