A vinyl sticker wouldn't work. You could get a patch with the iron-on backing, and iron it on. If you want just a plain test logo it would have to be iron-on vinyl. But the best way to apply that is with a heat press, which most people don't have. I can't say how well it would stick with just a regular iron?I'm thinking about getting myself a messenger bag to tote around my crap all day. The one I'm looking at is waxed canvas and I want to show my Test pride. Would the vinyl sticker adhere to that?
