I know there are differences of opinion, and I'm glad for those who don't have troubles with precuts. I have purchased a very few on sale, but even then they were expensive compared to yardage. I like buying a little extra fabric for my inevitable mistakes. I like knowing that I'm not going to have much more shrinkage after the quilt is washed because I've prewashed and preshrunk all the fabric. I'm also not going to have to worry much about colors bleeding. With yardage I'm not limited to pattern choices except by my abilities. I don't think it takes much time to cut strips or squares, and I don't have worry about them being cut off square. I've also been disappointed in the choices of fabrics in some layer cakes and charm packs. With one layer cake, there were 4 fabrics that didn't fit in any way with the other fabrics. There was one that didn't match any color and others that were juvenile patterns put in with rich reds. I've decided precuts are not for me.
