For this project, you'll need:
wooden squares (found at Hobby Lobby)
paint tray (I used a paper plate)
foam brush/paint brush with a precise tip
ball point pen
letter pages printed from this website:
I placed the printed letter on top of the wooden tile and traced around the letter and the small number, using the ball point pen, pressing hard. It's difficult to see in the picture, but below is what it should look like.
Using your precision paint brush, paint around the edges, then fill in the center with the foam brush (or whatever seems to work best for you). It does take a lot of concentration for each one.
The final product!
