The administration at my school has given me the go-ahead to cover an ugly section of wall in my classroom with cork. I think it would be easy to screw in a 4x6 piece of cork, and this would create an awesome place to display student work. Also, I figured a roll of cork had to be fairly inexpensive. HA! It turns out, it's some pretty pricey stuff! Does anyone know of a cheaper way to achieve this affect? Would ceiling tiles work and be cost effective? Or is there a supplier of inexpensive cork? I was only hoping to spend about $20. Thanks for any advice!
