Reading all these pro's and con's on Etsy and craft shows etc...... I sell at both. Yes Etsy is sporadic unless you have a huge line of a really hot item. But, I've made money on it and have done well prior to the holidays (when everyone is shopping). You have to know what postage is and either add it to the sale price of your item or price it separately.
I hadn't done the craft show circuit for a few years because of the economy but ventured just a couple of weeks ago and did very well. People look a lot but people are starting to buy a bit more also. It also helped that I can now take a credit card payment. If you want to sell high dollar items, that's crucial, (Check out Intuit GoPayment.com)
One of the newer places to sell online is Yardsellr.com (spelled correctly - no "e" before the r). I'm on there and many people seem to do well but I haven't quite figured it out with the points and all. If complicated, if you ask me. There is no listing fee and they only charge you when something sells but the listing doesn't stay up there that long so you're having to relist frequently. You might do well.
Just my 2 cents worth...............
