Well, since I was making storage pocket things, I decided to make a calculator cozy for my TI-89. I also needed a place to hold extra batteries, because I’d rather not be in the middle of a test and have my calculator die with no back up batteries available. Yes! This does happen! I’m still debating about adding the extra ribbons on top to secure the calculator, but I don’t know if it really needs it, because it fits pretty snug. I made this out of the Mars Martian fabric that I created. :) UPDATE: I decided to add the bows for closure. :)
