Hey, a sale already, well done! there are a few ways to get yourself seen;
1)renew items. It costs $.20 each time but puts your item at the top of the search results.
2)make treasuries, it's fun and a good way to network. You can email the featured sellers to make them aware, or it will also show up in their activity feed.
3) consider joining a treasury team to increase your chances of being in one. Other teams will also have team treasury challenges or chain games.
4) promote on facebook and twitter.
5) be patient- this part is hard- but as you are seen and hearted more, others will see more of you because of the way etsy set up circles. It is a very slow snowball effect. Hang in there and congrats on your first sale!
