If you have a thrift store near you look for old Simplicity or McCall's patterns...this paper is so thin and works wonderfully for string paper piecing.

Smaller stitches?

Thanks for all the great ideas!

I read somewhere either on QB or in a quilt book the idea that you can use a Q-tip dipped in water to slightly dampen the foundation paper and it will come off much more easily. I don't remember what kind of paper, but probably phone book paper or sandwich wraps from the big box store would be the easiest.
