Double it, I'll bet it took you a long time to make it. Suddenly it's turned into a business and you have to get something out of it. I'll bet that should you ask only 150 for the first guy, everyone else who sees it will want the same deal, no matter if they are ordering a baby quilt or a king sized one. Few people who don't quilt have any idea of what goes into a quilt, and are sometimes shocked to be asked to pay a decent price.
