For inspiration, consider listening to the band, My Bloody Valentine and eating heart-shaped message candy!
Let's just start this whole thing out by attaching the hanger to the back of the plaque. I often forget to do this until my projects are all finished, often making this a complicated endeavor. Just do it now.
Write out whatever Valentine-related thing you want to say to your loved one on the baby's forehead in pencil first, then carve over it with your X-ACTO knife. Get in there real good and deep!
Paint the baby head with several coats of white paint and the plaque with several coats of pink paint. Let it dry.
Attach the baby head to the plaque by: A) Putting a dab of E-6000 on the back of the head where it meets the plaque and B) Screwing two screws through the back of the plaque into the back of the baby head. While I had the glue out, I also glued my doll's eyes open.
Stain the baby head and the plaque. Mix a small amount of black and brown paint. In small sections, paint on a bit of the mix then quickly wipe it off with a paper towel. If you accidentally apply too much, just get the paper towel a little wet and wipe off more.
After the stain is dry, you can embellish the baby head with some colored pencil. You ESPECIALLY want to highlight the carved words in the forehead. With a supersharp red pencil, really get in the carved areas so that it looks all scabby in there. To make the baby look even more creepy, use red pencil around the eyes. Use the black colored pencil to add some shading around the carved areas and the eyes and anywhere else you think might be nice.
Coat the whole thing with some varnish.
Use E-6000 to attach ribbon around the outside of the heart and to attach lace around the neck hole of the baby.
