I'm glad you found a solution to your problem. This is one reason I don't like to "pre-cut" too much before I start sewing. I have been to classes in which I brought pre-cut pieces, and then found out that's not the way I want mine. In one class, I spent my time helping someone else. Those pre-cuts are still in UFO stage. In another class I found the teacher trimming off more than half an inch from the squares. I wanted to make the squares smaller or make my finished blocks larger. Since the stuff was "pre-cut" I chose to make my blocks larger. Turned out beautifully.
