I had hubby cut me some blocks from wood in the garage (luckily he saves all his extra wood). Then the girls and I went to AC Moore with a gift card for craft paper. Lucky for us it was on clearance and we scored 2 huge books!
Then a little Mod Podge on the paper/wood and let it dry.
They I made letter stencils (printed out a font I liked in the right size and cut them out) and made the letters with permanent markers.
