An alternative experiment to using jewels is to spray paint the egg shells gold..
This way i could produce elegant looking egg shells, but much quicker and on mass.
I have painted the egg shells as a whole, and also broken them up and painted them, so there are just fragments of golden egg shells.
I think maybe combining the two ideas, of jewels and gold together could produce a nice, very royal effect. So next i think I will paint the inside of the eggs gold and then put jewels on top also.
