Well, I do like pre-cuts. It saves me time cutting and wear on my cutting board and wrist. Also the cuts are very accurate. It challenges me use fabrics I wouldn't ordinarily buy. It also challenges me to design a quilt that only uses the number and color of pieces I have or to find a coordinating additional fabric. Its like working outside the box so to speak. I am very pleased with some charm blocks I just sewed up last week. Wish I could post a pic.
