I had my husband cut wood blocks 3.5 x 4 x 1 inch and sand really good so that we had no rough edges. I based coated with brown paint and let dry. I cut paper to fit each block, front and back.
The paper I used was from a $1.00 package we picked up at Target last year and I used Modge Podge to adhere the paper to the wood block. A good tip I found was to lightly apply a coat of Modge Podge to your paper front first and let dry and it really helps keep the bubbles down. I then cut the Cricut Alphabet uppercase on the font 3 button at 3 inches. I cut it from brown cardstock and attached with Modge Podge. I also cut some small leaves to add to the corners around the letters. You can do these blocks for any occassion or holiday.
