Thank you all for your advices.
I promote my brand outside Etsy using diferent social medias (Facebook, Instagram & blog). I show part of the working process, give some tips on how to proceed with some techniques, post my last creations and also pictures of people wearing them but I guess that it can always improove the comunication in this medias and post more links to my Etsy shoop.
Ass you suggest, I'll try to focus on my SEO. Before you sell, you have to be found.
Thanks again and have a wonderful wendsday!
