Sorry I didn't mention the pattern I just bought - I got it from Connecting Threads, thru the catalog. They are called "Mama's Pincushions".
It is a kit with 4 different patterns and 12 FQ's included. The patterns are:
Apple Core, Grandmothers Flower Garden, Honeycomb and Tumbler.
Y'all probably already have these patterns available and could just adapt them for the pincushions.
Thanks for the new sites too. I saw where you could buy the emery sand from one of them.
Very helpful, but I think I'm going to try the steel wool first.
