See? Add a self-adhesive border and transform a generic, boring bathroom into shiny awesomeness.
I don't recommend hanging these things while small people are around, as you may be tempted to mutter unsavory expressions under your breath. But all in all, this turned out better than I'd expected, if not easier than I'd hoped. I had to dunk the rolls in water for 10 seconds, which was supposed to moisten all the glue on the back. Except it didn't, so I had to add more water to dry patches, which was awkward and messy. But hey, it turned out cool and I didn't destroy anything in the process :-)
