I do a number of craft shows, this is the best time of year to do them of course, sometimes we do quite well, also I do home shows if they allow dirrect sales (not all do) the State Fair can pan out also. I have never done the Ren. fairs but have heard they are good. the key is haveing a huge diversity of inventory and a lot of it. A lot of the times those shows that charge more are the ones that you want to be in if you have the stock to handle a large show. In the mean time you might want to do some of the smaller shows to find out about your market, what sells at one show is not nessisarily the hot item at the next. Anytime I do a show this time of year I try to have $10,000 worth of enventory on hand, you want to charge twice what you would be willing to sell wholesale for, as that is what a wholesale buyer would pay you and you are incuring those expences in marketing yourself.
I have tried the web site but so far it has not paid off I don't have your skills there so maybe it could. Customers at the shows like it as they can see some of the stuff or show it to their spouse. I just don't seem to get the new customer there.
This is a significant part of my income and it may not really be what you want to do as you can kill your hobbie and may never make what you do in your day job. On the other hand you could make more than you ever did.
Just some thoughts. Mark
