One of the fun ways of promoting your products on Etsy is joining a street team--a group of people with common interests, whether it's a locality, a medium, or a favorite cause. Some time ago I joined the Etsy Vintage Street Team, which has been a great way of meeting and learning from other vintage sellers. I recently joined another team, the new Steam Team, which includes artists and artisans in the steampunk genre. Some are like me, with only a portion of their stores devoted to items that could be considered steampunk, whereas others are thoroughly involved in both the art and the lifestyle.
And it's been fascinating, as you can see from the above treasury curated by ClockworkCrow--such a variety of approaches. There's gorgeous jewelry but also interesting artifacts and wild fashion. Keep an eye on their new blog for ongoing interviews and highlights from Etsy's steampunk community (plus, if you scroll down, some more of my cool postcards).
