"Thicker skin"... What is this measurement?
Fur costs Chf 250; sewing machine the same.
Take a look at a saddler's sewing machine that can make clean (decorative) seams!
You'll never get one for that price.

She sews 12 layers of jeans but no fur? Then thank you for the info.

No, that's not possible. It is already difficult with somewhat thicker material.

I think I expressed myself a bit wrongly. I actually only want to sew longhair synthetic fur. She shouldn't have a problem with that.
