McKinney downtown doesn't have craft vendors during the Crankoff or during Scare on the Square. I think the only thing you'll find with them is the Spring Festival which I believe is named something else now. (I have played numerous times for them with my band). The 380 show is 3rd Mondays. That would be a good place to be although I think the rental spaces are pricey. Howe ISD has a show in September at the high school. You should contact them. They're cheap and have lots of local traffic. The Cottonwood arts festival is a juried show and the art is very high end. I don't know what you do but it's really not crafts. It's fine art i.e. oils, watercolour, sculpture, photography. Hope this helps!
