The summer of 2016, I found some MEDca wrap (1") for our hens' bumble foot problem (it was the least expensive of what was suitable). It works great, by the way; it's the equivalent self-adhering wrap to vet wrap.
Today, I used it on me! For those band-aids that don't stay wrapped around phalanges, this wrapped around the band-aid works great. I'm probably not the first one to do this, but there you have it.

Good idea! I'm always splitting knuckles!
