Robin,
Never fear where you buy your fabrics when swapping in this swap. The only thing we generally ask is to put your hand behind the fabric. If you can see your hand through it it is not going to hold up long term. I have purchased great fabrics from Wal-Mart, JoAnns and even LQS but everyone has different budgets and different availability based on where they live so please if Wal-mart fabric is what you have than that is what you use and do not feel bad for doing so!
Odessa I am with you luv! I have about 8 more to do I think and a few Quilt Bee blocks for March. Fell a little behind with all of Izabella's medical stuff in March!
Hugs
April
