DO NOT, I REPEAT DO NOT put your stuff for sale on etsy!!! Valve WILL take it down and threaten to sue if you put it up again!!
I have had this happen and as far as I can tell by the rarity of portal stuff on etsy and how short-lived most of it is, Valve WILL NOT HESITATE!!!
Do yourself a favor and DO NOT LIST PORTAL FANWORK!!!!! Unless you want “”“"copyright infringement”“”“”“” on your etsy record and possibly your permanent record!
This doesnt mean you can’t sell your awesome stuff; just either only sell at cons/other local shows, or let your followers know that you will sell your stuff and list it as a custom item for them (that’s what I do with my cores).
Please protect your self!! And spread the word!!!
