Clip a piece of sponge to a clothes pin and dip into paper cups, use the clothes pin as a handle. Lightly dab the sponge over the top half of the egg. Turn egg over and repeat procedure. Let the egg dry completely. If using blown eggs, spray with acrylic spray for a permanent finish.
Most retailers now sell plastic shrink wraps for egg decorating.
All you do is cut out the wraps. Slip over a hard boiled egg and dip in boiling water. Wrap will shrink onto the eggs. There are several designs available on the market.
