You can decorate hard-boiled or hollow eggs, but only hollow ones can be saved for future use. To hollow eggs, see step 1 of the wreath instructions.
Print clip art onto decal paper. (Open our PDF in Adobe Reader or Acrobat Pro to print.)
Spray the paper with two coats of varnish; let dry after each coat.
Cut out individual decals, staying as close to the designs as possible. Soak them in a bowl of water for about a minute.
Remove a decal from the water and slowly separate it from its backing, sliding it onto the egg as you go. Smooth with your fingertips. Gently press a paper towel against the decal to absorb excess water.
Let dry a few minutes; repeat with additional decals. Try multiples of the same design, or a collage of different images.
Let dry overnight, then spray with a coat of varnish.
