You can sell anything handmade. I have a shop. (if you want to see what the site looks like you can go to heatherg23.etsy.com.....It only costs 40 per item. It's very very easy to use and the listings are good for 4 months. Etsy gets a VERY small portion,money wise, on anything sold. It's practically nothing. People can send you messages if they have questions. When you add a product they take you through every single step 1 screen at a time. They let you add 15 keywords so people can find your store. I was really surprised at the amount of people that see the stores and the amount of purchases. I sell winter stuff right now and I had many buys in just a couple of months. Your page will also tell you how many people have visited each of your products. One last thing that I just found 5 minutes ago is that if you have a blog (which i do) you can have a "feed" on your blog showing your items. For an example of what I mean you can see it at http://knitting2008.blogspot.com
which is my page. It's on the right side. I also just found out that etsy has an application on facebook. They just got that up and running. That's extra advertising at no cost to you. That's if your ON facebook.
It's definetly worth the while.........let me know if you have any questions.
Have a good one!
