I started with a chalkboard from Hobby Lobby.
Then, I traced each line onto the board. I was so nervous once it came to painting the lines I would screw up so I used a pencil and a ruler to make sure it was all straight and perfect.
Then I began to paint the lines just right over the penciled lines.
And here is the scoreboard at the shower!
Instead of signing a guest book we had everyone "autograph" a basketball. I wish that had been my idea.
