I headed over to my local craft store and found some simple, beveled wood plaques. They were like a dollar (maybe 2) and they had one just the right size! I sanded the edges a little and painted it white (I did 2 or 3 coats, to make sure it totally covered the wood).
Then, I cut out a heart shape with my Cricut and used the heart to figure out if it was the size I wanted:
When I was happy with the size, I cut the paper with the heart "hole" in it, to the size of my plaque and I taped it onto the plaque, around the edges, with painters tape.
That made my little stencil, but I knew I would have to be careful not to let my brush get paint under the heart guide. I made sure to always paint toward the inside of the heart, to avoid that problem. After I had completed the project, it occurred to me that this would have been easier if I had used adhesive vinyl instead of card stock.
I used some metallic gold paint and did several coats until I was happy with the coverage, and then I did a few coats of a sparkly gold finishing paint that just gave it a little bit of a glittery look. I did the same thing with our K & T letters, to give them an update.
I was very happy with the way this little project turned out! You can see the changes we made to the whole bedroom by visiting the room makeover post.
