I think mine is magazines. I keep telling myself I don't need anymore cause I have plenty of ideas from the ones I already have. Add to that all the patterns I've downloaded from the internet. . . you get the idea. But I can't seem to resist "just taking a look" when I'm in the store. Another problem is that I can't seem to bring myself to get rid of any old mags. So I'm getting quite a stack! I tend to pick one up to read on the plane when I take a trip. Another trip scheduled the end of the month so I'll probably add another to the collection!
