Right now I have a Twitter account of 50k and one with 20k plus a few smaller ones, and I recently started an Instagram account that is growing fastly, so I figured Pinterest was the next step. I am selling Game of Thrones themed tshirts (no I don't have permission from HBO, just doing until/if they tell me to stop) and was wondering if anyone could explain how Pinterest works and what's the best way to make money on it by selling merchandise. I made an account but feel a bit lost at the moment. Thanks.
