As was said earlier, buy what you can afford, there are no quilt police, learning about fabric is a process and your likes and dislikes will change from time to time. The main thing is to enjoy yourself while choosing fabric and making your quilt. Learning is never ending and a huge part of it.
The fabrics that I bought that bled so badly, one was Windham and I've bought a great deal of their fabric before & never had any problem with bleeding. Never. I will cont. to buy their fabric because it is a good quality and I love it. The other 2 pieces was RJR Fabrics and I also will cont. to buy this. Never had a problem with any of theirs before either. Just test your fabric if in doubt and go from there. I always do a test on all fabric that I buy.
