Toilet paper rolls have many uses. The most handy is using them as cord minders for small kitchen appliances. They say leaving small appliances plugged in uses electricity so I roll the cord and insert it in a toilet paper roll . That way cords are not hanging everywhere. They can also be painted with any acrylic craft paint to match the decor of the room or appliance.
I also use them at Christmas as tree ornaments. Hide money or small gifts inside, wrap them in gift wrap with the ends twisted closed. Let the guests choose their ornament from the tree. They don't know if they're getting a ten dollar bill, a dollar store trinket or something valuable. This is also good for other parties. It's great fun. Almost everyone loves surprise packages. I've also put lottery tickets in them.
