My girls wouldn't like me using their tasty eggshells to start seeds. They love eating those shells too much!
My kids and I made "Eggheads" a long time ago. Crack the very end of the pointy end off the egg and dump the contents. Rinse and pack with vermiculite & dirt blend. Water well and then put grass seed in the opening. You can draw faces on the eggshell, and when the grass grows it looks like green hair. It's really cute (but hard to water as someone mentioned before).
