Smaller quilted items seem to sell well. Look around here for purses, wallets, wall hanging, table toppers, vests, TISSUE COVERS (tee hee), place mats, mug rugs, luggage tags, key rings, water bottle carriers, there's a huge list of small items that you can whip out without much effort.
Still sticking with spending money on one or two really good "how to quilt" books rather than a bunch of classes.
