I'm in a similar situation. Reopened in June and have had 12 sales. Four of those 12 sales came AFTER I quit paying for promoted listings, because I had not had a single sale as a result of them.
I think your jewelry is really cute. What I keep trying to do is get more followers, get more views, get more favorites and add lots more product even if you list some of the same items twice with different pictures. I think having 50+ or 100+ items helps. I hot 50 last week and am working towards 100 :)
