How to make faux mosiac eggs using abalone shell tiles . . .

These egg when finished are quite heavy; they
should be displayed in baskets or in vignettes,
not on egg trees.

        Traditional mosaic eggs made from plastic manufactured eggs, grout, and tiny mosaic Mother of Pearl pieces from Michael's. These crushed tiles have been sold at Michael's for over 10-12 years and come in many colors depending upon the year. 

Supply List:

• large plastic egg forms for the local hobby store or dollar store
• crushed abalone shell tile
• wood glue or tacky white glue or hot glue if you prefer
• tile grout, white
• Mod Podge

Step-by-Step Instructions:

1. When adhering the tiles to the egg shell rough up the surface of the egg with sandpaper and then glue on the tiles using a strong bonding glue. I believe that I used wood glue for these eggs. 
2. After the crushed shell has dried, smear on a tile grout and then use a soft damp sponge to wash away excess grout.
3. Let the grout harden overnight. Crafters may also use wooden eggs to replace the plastic ones if they wish.
4. Seal the grout with a thin layer of Mod Podge or something like it.
