My guess would be that they were looking for all fabrics in the swap to be of comparable quality so that a quilt made of them would look and feel right. Participation in the swap is voluntary, so if a person doesn't want to shop at a LQS, they wouldn't have to be in that particular swap. I like to shop at the LQS. They always offer a corner of sale fabrics, and I like to find great bargains there as well as regular priced items. I always try to support them because I would hate to see them leave. I also shop at Hancock's and Hobby Lobby which are in my hometown too. I want to keep the all. I loooooooove fabric!
