Eggs, anyone?

We are doing an Easter mosaic art project on Thursday, April 5th. I do have an unusual request. If you happen to be making a soufflé, a ton of pancakes, or anything else that takes a lot of eggs, please save your eggshells and send them to school - rinsed out - by next Thursday. If everyone brings about 4 eggshells, that should be enough. If possible, I would prefer them not to be cracked in a thousand tiny pieces; this will make the art project harder. Please click on the link below. It shows a shamrock, but the idea is similar. And again, please rinse the shells well before bringing to school!
