Oh yes, I LOVE playing with my stash. Not only when it's new; whenever I feel like I'm in a slump or if I'm just bored I just open my cabinets and start pulling fabric out. I like to play games...I close my eyes and dig my hand into my scraps bin and pull two random pieces out. Then the game is...can I find other fabrics in my stash that would make these two random fabrics "work" together? Sometimes yes, sometimes absolutely not, LOL. Or other times I'll just play with color combinations and let my imagination go crazy.
DH asks me what I'm doing, I just say I'm "reorganizing".
I do think it's a good exercise for putting colors together, but I'm not doing it to be constructive, it's really more akin to a dragon sprawling about on its treasure. LOL
