Have you seen those items that are popular right now? You know, backpacks, pillows, even binders for school... They have these little shiny scales sewn into them that can be flipped over to reveal a different color. Chances are, if you have a girl in your life, she owns at least one product with such a thing on it. You rub your hand across it and suddenly it's a new color. You use your fingers and you can even write messages on the surface.
It has recently come to my attention that they now have shirts designed like that. What delightful pedo thought it would be a good idea to have the surface of a little girl's shirt, right across her chest, be such that it changes if you rub your hand across it? Sadly, I know of no LGs with such a shirt that I can play with, but what a wonderful idea? I'm thinking that drawing a double heart in those tiny little shiny scales would be fun. :)
