Hi! I don't sell my crafts but this is what I've picked up on from people who do.
I'm not sure where you live but in Florida, where I am, especially Tampa. There's not a whole lot that goes on as far as craft shows, we only have 2 or 3 a year. Here and I believe most everywhere else though you can try selling your stuff at large farmer's markets.
You can go to http://www.eventlister.com/
or just google craft shows (insert city name here) that's what I did to see what was going on and they usually have info for interested vendors as well.
Also, it'll probably be easier to get advice from other sellers if you post on the Crafty Business Advice
And there's also an Opportunities for Crafters
I hope this helps
