So easy I almost fell out of my chair. In other words, you can do it too!
We were very fortunate to have extra slate leftover from having our porch finished this past year. The thing is, though, look around your house, I bet you can find something to use as a base. Wood, a piece of cardboard, etc. For the sandpaper, I went to a local hardware store but you could order online too. I wanted five grades to fill the slate base. You'll need some sort of adhesive. I used wood glue because I had some lying around the house. Wood glue, funny enough, actually worked fine in my case. I am sure there are other adhesives that may work better or just as well.
I cut five even pieces of sandpaper and glued the strips onto the slate and let dry overnight or a few hours. I let it sit overnight to be safe. I also placed a heavy book on the pieces to keep them down in the drying process.
Pretty, right? I saved enough sandpaper to cut out smaller pieces for my son to play various matching games (eyes open, eyes closed).
Even my seven month old enjoyed feeling the textures.
Thanks for reading!
