Hmmm, maybe that's why kilts are often hand sewn....

Could be the thread too....?? Know the hand sewn kiltmakers are very particular about their thread.

Having grown up in cut and sew factories know there's a huge difference between home sewing machines and industrial sewing machines. Did you see Robert's (RKilts) pics of his shop?

Course with most cut and sew now overseas may be hard to find even a used industrial machine.

Good luck.
