Here is one of the umm, lovely mousepads provided for my 7 student computers:
This one was actually in pretty good condition. Some of them were peeling apart much more than this one and a few had some lovely drawings and student names tattooed onto them... (good 'ole Kindergartners)
I cut squares of fabric and simply wrapped the fabric around the mousepads like a gift. I hot glued the edges on the back and did my best not to let things get too bunchy around the corners. Luckily the fabric I used was pretty thick so my fingers weren't singed too badly when I pressed the fabric down onto the hot glue. If you use thin fabric, definitely use a marker or some other tool to press down as you glue.

I'd love to know any of your DIY ideas for sprucing up your classroom! Feel free to share in the comments. ;)
