I’d be happy to make vinyl transfer stickers (different from the printed and then die-cut ones from Stickermule) at pretty much any requested size, going by either a desired width or height. Stickermule does also sell these, but I make them here in my apartment, so, hey - no middle-man.
In terms of smaller sizes, there will be a point at which my cutter will not be able to do the little key dots, but I think I can get them pretty small. About what size were you thinking?
They’re good for most surfaces but aren’t as good for stuff like sticker-bombing. Instead of being printed, they are cut and then kept in place with transfer tape until you put them on something - here’s an example from Google:
I’d be happy to send you and whoever else in the thread that might be interested some prototypes for feedback. Once the size(s) and such are nailed down, I can figure out what they’d cost to make for a larger run (or a small one) and set up a widget of some kind so people could buy them securely with PayPal or something here on the site.
I’m not sure how much interest there is, but I thought it might be cool to send any proceeds above my production and shipping costs to whoever keeps the lights on here at Keebtalk. I really appreciate this community, and in the age of popular aggregates and giant social media sites, I think this just might be my favorite place on the internet.
