Quilt books? Books are easy to find at a discount online that you have to find a way to get the shopper to want to make an impulse buy. At a vendor booth, I would want to see sample quilts or blocks made from some of the books. Something that would motivate me to make one. Call surrounding guilds and offer to come to put on a free program for their meeting. Guilds love free programs! You can have the books for sale at the meetings.
