It's a shame hearing sellers struggle with Etsy. I still frequent and love it there - everything from fabric yardage to gemstones and jewelry to antique clothing...it's like the best flea market ever, and yeah, so many talented artists!
That being said, I do know jewelers who sell via Instagram, or who rely heavily on Instagram to be the advertisement for their sales elsewhere (in Etsy shops). One guy just sells so many lots per week via his Instagram picture feed and IG's private messaging.
