I like crafts shows for the 'handmade' items. But, I also like craft shows where there are venders that sell items that are used by crafters, as in crafting supplies and the like. Like if it is a quilting craft show, I like looking at the different sewing machines, longarm machine etc., as well as the venders that sell patterns/fabric/notions. I'm able to find things that can't be found else where, some because it is a newly put out item.
What I don't like is venders at a craft show like those selling kitchen items etc, and those with nothing at all with making crafts.
