Here are some ideas that I found from one of my favorite sites... All Recipes!
Use a blown egg; dye desired shade. Gently expand opening at the top of the egg; glue a small flat rock to the bottom as a base. Hide glue seam with ribbon or beaded chain. Use hot glue to affix silk flower into eggshell--flower should just peeking out the top of the egg.
As simple as it gets: pick your dot color and place tiny dot stickers on a white or dyed egg.
Flower Power Egg
Dye egg. Use glue gun to attach flower sequins in a matching color (red on red, blue on blue).
Dye egg. With glue gun, attach large and small necklace fasteners to add a royal touch.
Dye egg desired shade; glue ribbon around its middle. Insert small tag or charm in blow hole and affix with hot glue gun. (The charm in this egg says, "Thank You!")
Dye and dry a blown egg. Dilute craft glue with an equal amount of water and paint on egg. Roll in superfine glitter and let dry.
Broken eggshell? Don't throw it away: dye the entire shell. With a hot glue gun, affix fuzzy chick figurine inside.
Die-cut stickers come in many different word themes. Mix and match words and themes to cover a plain egg.
Beads aren't just for clothes anymore! Dye egg in a bright color; glue faceted bedazzle beads in rows on half of the egg.
Using a hot glue gun, place glue dots all over egg. Let dry, then dye.
