I'm a shopaholic too! Well, actually, as somebody wrote, now I consider me a collector! I have hundreds of kits (I think, I've never counted them!), most of them never unzipped. I don't always make the same numbers of LOs. It could be that I make 1 or 4. It depends. I love mix and match elements/papers and recolorize them to match other papers/elements or photos.
As a CT, I usually make 1 or 2 (if I have time) but I could make more if I like a lot many elements that I couldn't use in the LOs I made.
I like designing kits, but I haven't started to sell them. So I make at least 4 LOs with my kits; just in case I'll decide to sell them!
