This genius idea just seems too simple. Create a pen caddy with toilet paper rolls and an old shoe box! Or, use them to organize those pesky cords. ( this page isn't found but I think you get the idea )
Cut a slit into a toilet paper or paper towel roll to make a wrapping paper cuff! (keeps the paper from unrolling everywhere). For smaller rolls, you may have to put a piece of tape on the outside of the toilet paper cuff to make it fit.
