I agree with Paper Princess - buy only when you need for a specific project. Kind of like fabric, there is something addictive about it and getting the darn dies. Those dies are expensive though, more than a yard or two of fabric. I have dies - probably 6 or 7 that I have never even opened and now I question if I will even ever use them. I use the basic squares and triangles often as well as those cute little birds (in my eye, birds make anything better) but I have never put a bird on a quilt. I do love the alphabet though but boy those were down right expensive. Other than that, I have never used the flowers, the dog, the cat, the little Christmas house etc. Make friends with someone who also has one, that is what I did, now we share.
