Classes are good, sunrise - I mean we have to help the economy somehow. As long as you don't buy kits or new fabric just to do the class.
Joe'smom - my very first class was a sampler class, only I hadn't read that it was a scrap sampler. Silly me, didn't own a single scrap. Well, THAT problem was soon solved. Unfortunately I went on a "oh I love that - give me a yard" "Oh I really love that - give me 5 yards" buying spree that lasted a few years. I wish someone had told me to nip it in the bud. Stash has a tendency to grow without much effort.
