I got plain wood blocks that we fairly cheap.
Then simply pained them black. I didn't paint the front because it will be covered with paper later on.
Finally I used Modge Podge to attach the scrapbook paper. The great thing about wood connection is they have all the supplies right there in the store so you don't need to make any extra trips to a craft store for paint or paper.
One little tip when applying the scrapbook paper; make sure that when you trace your object, in my case the letters, that you are tracing it the right side up. I put the letter down and ended up having to retrace all my letters because they were backwards. Good thing I hadn't started cutting the paper yet.
It didn't take long at all and was super easy! I thought it turned out pretty cute! You do not need to put anything over the scrapbook paper. The possibilities are endless with this technique and it looks super cute and professional.
