I know in Canada, handmade crafts, don't sell for much money. Like my fellow stitchers' commented, more often than not it costs you more money to do the project, than you would make selling it. Before you start selling your projects look to see if there are any copyrights laws that you may be infringing upon. I don't know how it works in the US but in Canada if it is your original design you are able to sell it. However if it is a design from somebody's pattern or kit, and you make it you are only allowed to give it away as a gift.
Good Luck with your sales!
