I have started using Society6 as well as RedBubble. l am still looking for a good quality maker for stickers and do want to order some prints to list on Etsy and send to a gallery which has my work in Arizona.
So if anyone has sticker makers they have worked with and like the quality of what you have gotten please let me know!

I've used red bubble, they came out decent. Though sorting out how they resize stuff is confusing. You could check with con chairs see where they get their decal like stickers from.
