The other day, I was in a Walmart for the first time in ages. The $1.50 yd fabric was either polyester or unknown and the $2 yd stuff that was 100% cotton was so thin you could read a newspaper through it. Now, that being said, I bought several yards of the $2 stuff because I wanted to try a pattern and didn't want to mess up my good fabric. Sadly, it was so thin and flimsy I had to spray starch the heck out of it and I'm not even sure it will hold up to washing for a charity blanket. It was not easy to work with.
