At a recent playdate, I wanted to experiment with marbling paper using the shaving cream technique. (Thank you Teri for sending me a link!) What absolute fun!! You basically take a shallow pan (I used an aluminum pan) and fill the bottom with a layer of shaving cream. You don't need too deep a layer of shaving cream--just enough to cover the bottom. You can use a spatula to spread the shaving cream into the empty spaces.
You can use food coloring or acrylic paints for this technique. I thought the food coloring would bleed too much so I chose to I use cheap acrylic paints. I chose three complimentary colors and placed drops of paint sparingly onto the layer of shaving cream. Using too much paint will smear. Now comes the fun part. You take a mark-making tool ( I used a skewer stick) and begin to move the paint around on top of the shaving cream to gently mix the colors. I found that keeping peaks in the shaving cream yielded the best results. If you smooth out the shaving cream till its flat, you will not get the pretty marbling effect.
When you are satisfied with the pattern, place a sheet of paper on top of the shaving cream. Gently press the paper into the shaving cream for full coverage. Lift the page and let sit to dry for 3-5 minutes. If there is enough paint left, try to pull a ghost print. After the page has dried for 3-5 minutes, take a squeegee and remove the excess shaving cream from the page. What you have left is a beautiful marbled page!
