I found out many years ago that fabric company make alot of different grades of fabric that how Joanns and WM sell them for cheaper. I really have a hard time buying from the if I'm going to make a quilt to last into the next generation by using them and all the time it take to make a quilt too!
I used Joann fabric on a quilt for my Daughter for her wedding a 2 color log cabin it was 120x120 a big one and with in a few years it all balled up on the top and the seams were coming apart. I did the washing of it and know I did a good job doing that. It made me sick as they loved that quilt!
