First let me say that I think its great that you want to sell you crafts out online. Second let me tell you that I have done this before. However, I didn't create my own website, I have sold my items out on Ebay. I have had some success along the way doing this. So, this is the suggestion that I have for you, if you aren't sure how to draw traffic to your own website, start out on a tried and true website that already has the traffic.
Ebay is one of them, there is also Amazon and Etsy. Etsy is pretty good fit because it deals with a great deal of handmade items. Once you start to build your reputation get customers who seem to want to continue for your items, then its time to create your own website. For that matter with Ebay you could create your own store through them, I think Etsy might have the same service, don't quote me on that though, I'm not too familar with them. Yes, there could be a montly fee for having this store but if you take your time to build your repuatation building your customer base before hand it might be worth the investment in the end.
