I don´t know exactly where I got the idea for this nintendo case from, but when I saw Shannon's, I thought I put it to hers..
It is handsewed and not the best, but I like the way it turned out. To make it safer for my boyfriend's DS, I sewed an old towel into the middle part of it ^^ *g*.
It's also got a little pocket for a game-cartridge and some rubber bands to hold an extra stylus.
