I have just opened a shop at Designs by Humans (DBH) this month. They are selling apparel, smartphone cases and art prints. There are two small disadvantages about DBH:

  1. Paypal verification for your shop costs $1
  2. You are limited to 60 designs in your shop

Apart from that I read from various sellers that they seem to sell mainly t-shirts. I am currently uploading the best of my designs to fill my shop. Please take a moment to check it out and please follow me. I am actively following back (on every site, by the way!).
