When I go to quilt shows I usually go through the vendors fairly quickly and if something catches my eye, then I make a note of it and if I still want to go back later I do. Remember you have to carry anything you buy so sometimes it is best to wait and buy it later. It also helps avoid the total impulse buying. And if there is something you want to find make notes before you go and then seek out the vendor. I had wanted to buy the Accuquilt Go but wasn't sure, when it was demo'd I bought my Accuquilt Go at the Road to CA show and got a great deal on it and several dies and the following year I wanted to find out more about the embroidery package for my Viking Topaz - once it was demo'd I was sure I wanted it. Once you pay for your entrance into the show, you spend as little and as much as you want. Just be sure to treat yourself to a souvenir. They usually sell bags or pins for $10.00.
