Etsy treasuries are collections of items listed on Etsy put together by Etsy members. Anyone can create a treasury, and sometimes especially well-designed and thoughtful treasuries make it onto the home page of Etsy.
One of my bracelets is part of an Etsy treasury put together by Etsy member KandiceInWonderland. Please be sure to go take a look! Not only does my bracelet look great in this treasury, but it (of course) features other very, very talented Etsy artisans.
