Here's how to make a super easy cork mouse pad...
Grab cork squares at Lowe's about $9 for a pack of 4. Make multiple mouse pads to give as gifts or use in different rooms of the house. I was tempted to just use the cork as is but I went ahead and spiced it up a little with some paint. You could even use the extra squares on your wall for hanging up art or other inspiration - or as a charger for a place setting - or as a matte for a frame - you get the idea, so many uses!
I went with two colors and the natural cork - acrylic paint and spray paint. As far as even lines - the spray paint definitely was easier and less of a mess. I decided to paint the entire square so I could pick and choose which area I would actually use when I cut it out.
