Q&A for How to Carve an Egg

You can cut it with a dentist drill following the line you draw on it at the equatorial line.

The Dremel tool is available at any store that sells hardware. An engraving tool can also be found in crafts stores.

It depends on how stiff you want the eggshell to become. A quick hardener would be quick dry nail polish. If you are doing a large quantity of eggs, a polyurethane or acrylic would work. Craft glue that dries waterproof can give a thicker layer to the interior that is also slightly flexible. General washable craft glue can also be used and can be washed out later.

A knit fabric like velvet, can stretch in different directions to cover a curved surface. Woven fabric like satin will not stretch and needs to be cut to the right shape. Rubber cement will allow you to reposition the lining as needed. With felt, use strips with tapered ends to adjust for the curved surface of the egg. Most craft glues or a hot glue gun can be used to secure the lining of choice.

Don't remove the membrane. Try putting the egg in vinegar, wait a day, take it out, and wait another day. The egg will turn to rubber after you peel the shell off. Also, if you peel the membrane, the egg will likely bust.
