Begin by painting the whole cork white and letting it dry.
Next, pull out some pages from an old book and cut them into small strips.
Paint the top of the cork with mod podge, and then decoupage the book page strips on to the top of the cork to create the cap of the mushroom. Paint another coat of mod podge on top to seal the book pages.
While the mod podge is still wet, dip the top of the cork into glitter.
After the mushroom is fully dry, screw one of the eye hooks into the top for hanging on your Christmas tree, or leave it as is to place on a stump
