I've got it by color, then I pull and put in a basket what I want for the next quilt. Then after I'm done, I put it back in its color section. This works because I never buy an entire line to make a quilt. With the exception of AB "Love". I did buy that all together, and haven't separated it.
I wanna live at Tinkle's house though. It *is* like a quilt shop! :D
