Step 1: Start with a 2x4.
Step 2: Cut the blocks to the size you need. I pre-measured the letters to know what size to cut the blocks. (My dad did the actual cutting. Thanks Dad!)
Step 3: Sand the blocks. Andrew has this power sander, and it got the job done very quickly.
Here are the blocks after I finished sanding them.
Step 4: Paint the blocks. I chose pink and green to match the nursery decor. I used just regular craft paint, nothing fancy. I did have to do 2 coats though.
Step 5: While the paint is drying, cut out scrapbook paper for the front of each block. I cut the paper a little shorter than the actual block. I just thought it looked better that way.
Step 6: Cut out the letters. I used my Cricut to cut them out. I actually did this first, to know what size to cut the blocks.
Step 7: After the paint has dried, glue the paper to the block and then glue the letters to the paper.
