Hi Taylor! Thanks for the info about Park City. I'll have to look into that. I just sent out my application for Summerfest since the deadline is in just a couple of weeks. I've heard lots of good things about it from people who attend as shoppers and it's a really good price for a two day show ($100). I'm still not entirely sure how it will go selling-wise, but I guess every show is a bit of a gamble.
I also submitted an application for the boutique that's part of Lehi's rodeo week. I don't know anything about it other than that it is 3 days and the rodeo gets a huge crowd. It's cheap, though, so why not? :) They are both in June, so I'm not sure what I'll end up doing if they both accept me. If you're interested in a less expensive show that should (hopefully) have a good crowd, here's the link to the Lehi boutique info:

Good luck with your craft show ventures!
