Just something I forgot I did once...for those making customized school supplies:

We had these pens, at work, the kind with the clear barrel, so that you can see how much ink is left in the pen-or whatever the purpose of that is-, (not the felt-tips..just 'regular'), and you could unscrew the tip and the end....well, to make a long story short: I was bored on night, and decorated ours, by drawing a picture and, after unscrewing the bottom of the pen, inserted it inside...everyone thought it was cute, and, if you wanted to get REALLY crafty, you could decorate them with glitter/stickers...whatever will fit.
