The keys to JoAnn's and Hobby Lobby shopping are 1) knowing what decent fabric feels like and 2) never pay full price. I use a lot of their fabrics for backings. I won't set foot in a WalMart, but I'd use the same rules if I did. I have no trouble mixing fabrics from different locations. The table runner I just posted had newly purchased LQS fabric (the sunflowers), Northcutt from my stash (the yellows) and Hobby Lobby fabric (the grays). It all worked out after the fabrics were washed and pressed.
