I'm getting ready for an upcoming craft show and today my order of 100 egg gourds arrived from a farm in Michigan... I'm sort of weird this way, but I thought they were really beautiful. They were amazingly uniform, and looked just like chicken eggs (albeit, with moldy skin on the outside :) Unlike eggs of course, they have hard, thick, resistant shells. They don't break easily. Inside, there are seeds that rattle around when you shake them.
Cleaning the egg gourds is really easy. I just put them in the sink for a few minutes with a couple of tablespoons of bleach, covering them with a towel so they stay under water. Then I scrub each one with a copper scouring pad. (Copper's good because it doesn't rust and because it conforms to the shape of the gourds.) I always wear gloves, especially when working with bleach.
Now I'm going to start decorating them!
