Painted using markers on egg shell. Made little hole and took out the egg. That is an omelette now.
Step 1: Make a small hole in the big end of the Egg shell.
Step 2: Take out the egg through the hole. You can use a knife to cut the membrane of the yolk if it does not come out.
Step 3: Wash and dry it.
Step 4: Stick the broken part of shell using adhesive. I used Fevicol.
Step 5: Make sketch on shell using graphite pencil if necessary.
Step 6: Paint on the shell. I used permanent markers.
