Most of my social stuff (twitter, FB, blog) is pretty dormant at the moment. The only one I use regularly is Pinterest. It's a personal account, but I do occasionally post a vintage item from my shop.

I have over 250 boards and over 37,000 pins so there's lots to look at (art, decor, vintage etc.)
I also have a website for my art (I have two art shops on Etsy).
