dry erase with cardstock, laminating, and duct tape - Just place the plastic sheet over the cardboard and tape around the edges. Simple as that and you're done. I was able to get 20 done in just over an hour sitting and watching TV. I love how cute they turned out and they are easy to write on/wipe clean. Plus between the presentation board and two rolls of duct tape it cost just over 50 cents each. I need to do this.
