Good for you...yes, working with leather is a challenge. I sewed patches on leather school jackets every week for a year. it was a great contract i had with a School Sports shop, I don't miss that . Sometime the patches would go way down the sleeve and I didn't know what would break first, my machine or my sanity!!!!

When I sew with leather, I use a needle made for leather. It has a different point on it so that it goes through the leather. I hope this helps.

I agree with Catherine--I've used my Bernina (not a real fancy one) to sew patches on leather just like she described and I had no trouble. I didn't even think about not being able to do. Guess I was lucky but it worked fine.
