Might be worthwhile for locals; not too much spending
Pound 2016 is, first and foremost, a Super Smash tournament. Most attendees seemed to go with gaming, not shopping, in mind. If you are interested in tabling at Pound, I'd consider the following:
-Most attendees are teenage boys on a budget, so have a good selection of cheaper items.
-Most tables were selling perler bead sprites
-There were a lot of out-of-state competitors who were worried about transporting their purchases back in their luggage
-Attendees liked hanging sprites of their 'main' from their controller or badge, so having some keychain type things featuring Super Smash characters might be a good idea.
Since I sell small, delicate and sometimes 'girl' polymer clay sculptures, this was not the show for me. But, a local artist with cheap wearables could probably make money. And be sure to bring your own food! Tyson's Corner is a very expensive area of NoVa- trying to get breakfast/lunch/dinner there 2 days in a row could really cost you.
