Here's a tip for newer tablers: some artists are willing to trade. You can walk around with a few samples of your wares, and if you see something you like at someone else's table, you can ask if they'd be willing to exchange it for one of your pieces. Not everyone can manage this, which is okay, but sometimes, you'll get new things without spending money AND get your work in another creator's hands. It's win-win.
Rock on, guys, and never stop drawing.
