If you want to re-use of waste egg shells, perhaps embroidered ribbon stitch on the egg shells can be your inspiration. First you have to do is clean up the eggshell, drawing the design motif and drilling the hole . As your embroidery on the egg progresses, the angle in which you exit the egg and re-enter will change, and so you have to seek out other holes to exit and re-enter the egg. You want to find holes that will allow you to move the needle in and out, without creating pressure on the egg due to a strange angle on the needle.
