I have done that very thing! So I have these pieces that are so difficult to cut, because they have to be saved for "the perfect project". It helps me cut into it when I imagine my estate sale (so many years in the future, I hope!) and the salesman saying to the purchaser "She DID have a lot of beautiful material, and never used it--I don't know why..."
It helps me make the first cut, morose, I know, but it works....:)
