As a relative newcomer, I still have tons of questions about every little thing I might do. It occurred to me, after seeing this category, that it would have been a giant help to me to just see examples of working artists' booths in one place, instead of searching around for information. I'm starting the thread by showing mine, and I hope others will add theirs. It really could help someone.
I know my shot isn't perfect. What is good about it definitely came from advice I found on AFI. I can say that while it is imperfect, it got me into a great show. I had to borrow the tent and walls from a friend because I still don't have my own tent (with only 30 days before the great show - yikes!), but I think it came out relatively well.
