Well why not try both.? If you are getting your supplies in bulk, and making the items yourself, then your profit margin should be enough to compete on ebay....
Try selling some of your stuff at a very low profit margin on ebay and use your 'about me' page to send some traffic to your website where you can sell a wider varity of your jewelry(and no listing or fvf's). Also keep a customer list of your successful sales on ebay and promote your website sales to that list...
