Etsy has created & made available a shop critique form. I thought this was particularly cool, seeing as now we can easily evaluate each others shops, (at least, in English!).

Also, Francesca created a LOVELY earring wire tutorial that I thought was pretty swanky. You can check that out here: http://www.bsueboutiques.com/pi_handmade_ear_wires_francesca_watson1.shtml
