You can use any kind of board (or even stiff cardboard), but here I used "Woodsies", sanded pieces of wood that I found at Hobby Lobby in the unfinished wood section. They come in the exact size shown here; no cutting needed! I then went around the house and gathered all of the textures I could find that I could cut and glue onto the boards. Easy! I made Ty's two-sided and all I needed was simple white school glue.
Top board: Glass bead material sample, fleece, bubble wrap
Middle board: Colored rice, contact paper sticky side out, cupcake holder
Bottom board: Corrugated cardboard, tin foil, scratchy outdoor carpet sample
Top board: Salt, sandpaper, birdseed
Middle board: rough cardboard with raised glue stripes, crepe paper, pipe cleaners
Bottom board: Felt, styrofoam, soft carpet
To my surprise, the colored rice, birdseed etc has stayed on really well. I did let the boards dry for several days before Tyler touched them. The carpet pieces are from Lowe's. They are free and I've also used them for texture matching activities! The only problem I've had is getting the bubble wrap to stay, so if anyone has any suggestions I'd appreciate it! I may just need to put something else in it's place.
