Today, I went up to a famer's market I've been frequenting almost weekly, it's a small venue, but there's always been a couple crafters there, including a fellow mailler. I sit, talk, absorb the experience, make contact with people, and generally have a good time while promoting the art itself. Out of respect for Glendon I try to avoid talking about my work with his customers.
I'd have a table there, but the market season only has two months left around here, and I don't really feel like I have enough completed and ready to sell to make it worth my time at the moment. However, it's only a 10$ registration for the entire season of May through October.
If you're a crafter of any sort, and in an area where farmers' markets are a regular event, especially when they're hosted at parks or something similar on a weekly basis. Find out if they accept vendors of handcrafted goods. It's not expensive, you don't have to show every day the entire season, it's probably local so you won't need a hotel, and you'll see people on a regular basis, and get to know them.
I had planned today, to feature a host of photographs of awesome little handmade things and plenty of maille by Glendon. Instead, I found... that they were unusually not present at all. Disappointing in a sense, but I got a Dremel out of the whole trip as a birthday gift. Diamond wheel and stainless, anyone? ;>
Back on topic, check around. State.gov or chamber of commerce websites might have lists of local farmers markets in your area, it's not a massive craft fair or a gaming con, but it's a good place to hand your name out just the same.
