First, I found the bottom of an old lamp that was headed for the garbage. I completely took it apart. I made my own decoupage, simply because I wanted to.(I have a whole bottle in my paint cabinet)
First, I tore my old newspaper into shreds. You could use any kind of paper you wished to. Into a big mixing bowl, I took 2 cups of flour, 1/2 cup of salt, enough water to make a paste, whisking it the whole time. When I got to a glue like substance, I started dipping the newspaper strips into the watery "glue" soaking them on front and back. I next applied each strip to the head, shaping it and molding it into each valley. Once I had the head covered to my liking, I washed my hands and cleaned up my mess. (could have used gloves, but I always like using my hands) I set the head on a metal pan in my spare bedroom for several days to dry. Drying time depends on the amount of heat the head gets.
Once dry, I cut out a hole in the bottom of the head that would fit over the top of the old lamp bottom. I filled the hole in the head with Gorilla glue and positioned the head on the stand. I returned the stand with head to the old pan and set it back in the bedroom, checking periodically for seepage of the glue. When I spotted any, I would just wipe it away with a damp cloth. Once the glue was dry and I was satisfied that my head would not fall off...heeeeee, I decided to paint the bottom of the old lamp black. I used acrylic paint and it dried quickly. I proceeded to apply the polyurethane to the head with a paint brush. I ended up with 3 coats, letting each completely dry in between times. I imagine you could use spray polyurethane. Then I covered the old lamp base with one coat of polyurethane and let dry. I screwed in, and used glue, 4 screw hooks on the back of the head to hang necklaces on. I LOVE MY BEAUTY.
However, I seem many imperfections in applying the newspaper and I will be more careful next time... Happy Crafting...
