This has always fascinated me and I have tried to do it myself personally but the tediousness makes it so very difficult. I guess for now I will have to do with adoring these creations from afar. These are created by blowing out a contents of an eggshell by drilling a hole at the end of the egg at each of its tips. The egg must then be dried. A variety of eggshells can be used: ostrich, emu, rhea, goose, chicken, and a variety of others. These can even be purchased dried and ready to use from some internet outlets. The usage of a Dremel (or preferably a high speed drill such as a dentist tool) . You must also use a face mask and a ventilating system to avoid getting eggshell dust up into your respiratory system which can make you very ill. The stands that they use are just as intricately created by making something from scratch, using antique candle holders, and other unique holders. I have only tried using a Dremel but would love to get my hands on a high speed drill it would be great to create something so special.
