i have a bunch of half-baked invisibility merch ideas floating around and so your flailing is helping :)

(also I love your idea)

I also yarn-bombed my walker, which is great because when people get the awkward "why is a young person using a walker" the words of awkward out of their mouth are "oh that is interesting...yarn?" and then we talk about knitting and not yet another conversation "why yes, I *do* use a walker, and no I don't want to talk about it."

I can definitely see writing up some crafty "how to decorate your accessibility device so the crafting becomes a conversation piece instead of how sick you are" kind of how-to's.
