I heard this tip at our guild meeting so I got some, and it works nicely....Delicatessen paper. I got mine at a GFS, which is a store that caters to restaurants, so Sam's might have it. It is the thin paper that butchers grab meat with, or that you can select your own donut at some stores (unless you're kind of paranoid like me!). Now I need to start piecing!!
