You will need a box of soaps that have sliding cardboard sleeves that surround each bar of soap. (I found a 3 pack for $2.99 at Marshalls.)
Cut a strip of sheet music (or scrap booking paper) to fit the cardboard sleeve and mod podge it right onto the surface.
Next, dab a bit of glue on each end of your sheet music "box" and add a layer of glitter.
Then sort through your scraps of ribbon, tinsel and holiday picks.
