Idea Starter: Clever Uses for Electrical Tape

Short explanation: This is an "Idea Starter". It's a small idea that I think has bigger applications. The point is to get you involved. I know you must have great ideas worth sharing, so take this and run (and then comment on the running outcome).

Electrical tape is amazing.

It comes in tons of colors, it's slightly stretchy, water resistant, does not damage most surfaces, and can be bought for $5 or less a roll.

My first adventures into electrical tape started close to its intended use - covering the old, ugly switch plates in my house.To do this, first remove the plate from the wall. Cut strips of tape about an inch longer than the switch plate. Starting on one edge and with a half inch overlap on both sides, slowly smooth the tape over the cover. Fold the ends over the edges on onto the back of the switch plate. Slightly overlap each previous tape strip and be sure to stay as straight and even as possible, use a metal edged ruler if you need it. When you get to the holes, smooth the tape right over them. For the switch holes, use an Xacto knife to cut a line from the top right to the bottom left, then from the top left to the bottom right (AKA make an X). Smooth the each little triangle flap over and to the underside of the plate. Just poke a little hole on each screw hole, the screws themselves will take care of those. For the left and right edges, let the tape have about half an inch extra space on the edge, top, and bottom. Cut small slits from the outer corner of the tape to the corner of the plate. Cut off the slit flaps (oh, that sounds so dirty!), and fold the overlapping tapes onto the back of the plate. When you put the plate back up, do not screw it too tight or the tape will twist and wrinkle (trust me on this one, it's impossible to re-smooth, just don't do it!)

This is super handy if you are living in a rental place with ugly switch covers because it won't damage the plates at all and the tape is cheaper than all new plates. You could probably use this trick on plug covers as well but I haven't ever tried. Did you try? Let me know how it went in the comments!

Other things I considered but did not take the time to do:
Alternating colors!
Varnish over the top to make it permanent!
Painting the screw tops to hide them!

What non switch plate related options are out there? Surely the magic of electrical tape is applicable in other areas of life.
