I hadn't heard about ruler folding for fabrics, so I'm glad the method was described. I may just have to organize my stash again - for me the feeling is what I imagine rolling in money is like. Should I organize by color? by theme? by end use? So much fun!
Re the I Spy question - I've made several "I Spy Through Attic Windows" quilts and have started to make them with themes. Just finished one with only farm animals made for a baby whose parents are large-animal veterinarians. I think one with Laurel Birch animals would look great too, as would one with a transportation theme.
