I used to have a real problem with that when I first started quilting. Would wind up getting out of bed and looking through books, mags, etc or just walking around my sewing room looking at projects in the works. Now I only do that when I'm starting a new technique. Like when I first started learning to McTavish. I couldn't stop my mind from doing the design over and over, so sleep wouldn't come easily. Had to get up and look at her book or try another swatch.
