Have you heard about instacanv.as? Well, on this site, you can sign in as an artist, then select your items from instagram that you want to sell. You may browse on to http://instacanv.as/ for further information.
Certainly I have a page there as well. You may visit my page at http://instacanv.as/tfenerci to see my items. Of course I’ll appreciate even more if you buy any of them :))
