I just found another great idea for decorating your shelf markers--duct tape! Here's what Renee at Books -N- Bags created.
You know that duct tape comes in all kinds of colors and designs now, right? On the Duck Tape website, you can find duct tape in all of these patterns.
I could also see using a strip of duct tape to identify the shelf markers for a class or grade level. Okay, maybe not the skulls in elementary school, but the zebra or polka dots?
