Sticker rewards? (Patreon)

I've seen a few other creators offer stickers every other month as a tier reward. I'm looking at using a vendor that isn't Patreon to see if I can go more risque. 

I was thinking of doing a poll one month where you all can choose the character and one of three offered poses, and then the next month the sticker would be sent out. I don't imagine the poses will be to explicit, but still nice to look at. 

I'm still working on the logistics, but before I get to far, I thought I would get your input.
