My advice would be to go to Joann's and experience for yourself the quality of fabric. If you are happy with it, then by all means purchase it!! Not everyone can afford to purchase fabrics that are more pricey. I have purchased fabrics at Joann's as well as WalMart and I do purchase a great deal online as many have said, the prices are sometimes more affordable. But... you do get some surprises, mostly on color being different than what your computer screen shows. I'd say take a trip to Joann Fabrics and have a great time seeing what they have!!
