Oh, that's really cool! I have been wheedling about trying to build my own kites. I've had a 3D printer for a while, and recently acquired a nice sewing machine... I might give your indoor model a shot this winter. I love some of the more custom patterns you've made, especially the plaid and the "deal with it". Very inspiring!
Unfortunately I am busy the weekend of that festival. I was also busy the last couple times I've seen festivals down in NJ. I need to look further ahead and get one on my calendar before everything fills up...
