Oh gosh, I must have hundreds of quilt books. Techniques mostly, but also use of color, composition, dyeing, history of fabrics or quilts, books on quilting from other cultures ie Japanese or African. Not too many books with just patterns. I'm always hoping for a new wrinkle on a technique and I love to see what other people have done. Lately my buying has slowed down, as I now have 6 shelves full of books! Kathy
