Disclaimer: no cels were harmed in the making of 
keychains.

I went to walmart today to find materials for 
the window cling idea. Although I didn't find 
what I was looking for, I did find sheets of 
shrinkable plastic. For those of you who can 
recall the era of shrinky-dinks, you can color 
this thin plastic with color pencils or 
permanent markers, cut them out, then bake them 
in the oven. The baking both shrinks them and 
makes them thicker, thus making perfect 
keychains. Below is a keychain I made off of a 
Xelloss cel sketch/cel. The to-scale image of 
the cel can be found at the URL link.

The only problem is that the blank shrinkable 
plastic is only around 1/3 the size of a 
standard sheet of paper, so only small images 
will work. On the plus side, 2 sheets of the 
blank plastic is only 99 cents.
