Diamond painting involves using a stylus to pick the multi-colored "diamond" gems provided with this kit and place them on an adhesive Design Sheet to "color in" the illustrations in the Sheets. There is one Design Sheet of dinosaurs and another of unicorns, plus more than 1300 "diamond" gems in different colors to choose from. When the gems have been applied to the Design Sheet, you just insert the decorated sheet inside the lighted base, then turn it on and enjoy the beautiful light you have created!
