Using some Rit dye, you can customize your Wiimote's straps. I went with Blue and Fuchsia, and at $4 per color, that's not a bad investment.
Step 1Go to the store and get some Rit dye.
I figured that dark colors would work best, so if you get yellow, you may be sad with the results. Take your box of dye home, and mix it with 1 cup of boiling water on your stove top. Keep the mixture on the stove, and then stir in your strap(s) (I found that 1-2 straps per bath works the best). Stir it around and make sure you move the plastic on the strap around or you'll get a light spot. When you're happy with the shade, rinse the strap under hot water until it runs clear, then under cold water for a few seconds. Let it dry and you're done!
For moving the plastic thing around, I used two forks I didn't really care about. That was how I handled the whole thing. I made sure the toggle was near the end when I started so that when I scooped it up with one fork, I could push it down with the other.
I've only dyed one so far, but I plan to do another tonight - Either red or purple, I haven't decided (the first one is blue).
