Here is what we have done today. Make sure you wash the egg shells first, before gluing in an oval shape constructions paper. DD colored and made all the design in the background and all three kids sticks the egg shells. You can also paint the egg shells after gluing them. I did not let them do it here because we already have a very colorful mix (white, brown & light brown). I used to do this when I was in grade school too. I made a drawing of anything and glue egg shells on everything before painting them. Enjoy.
