I agree with you. When I make kids a quilt, I know it's going to be lovingly abused. My niece made her first quilt last week, loves it, but decided it was too small. Then she started thinking about who she could give it to. One of her choices was her dog...a puppy who chews things up! Her worldly older brother (8) told her that was a bad idea.
I use walmart fabric a lot and have not had a problem yet.
