My husband and I own our own vinyl cutting business and we have been cutting black vinyl on a white background for teams in our area. These stickers can then be put on any surface. Picture
here. They're made of a vinyl rated for outdoor use for 5 years so they should stand up to two or three events
The team I mentor is sticking them on colored, corrugated plastic.
We had to update our branding and design standards to accommodate for them, but we're looking at them as license plates - you don't put it on your car because it looks good, you put it on because you want to be able to legally drive it.
