Getting back into eBay

Continuing to downsize after my recent move I am getting back into selling jewelry (new and vintage). I discovered these resources: http://www.indiemade.com/category/resource/general

and sites
http://www.etsy.com/
http://www.zibbet.com/
https://tictail.com/
http://www.rubylane.com/jewelry

Could they be more lucrative than eBay? Is it better to use these or have your own website? Time will tell.
