Making something over & over again IS tediuos to say the least. I HATE it lol. To make something as mundane as dragon eye's i use a tried & tested foil copying method. Below is how i make & copy a large pair of eye's.
To begin with i use card stock to make the eye lids & variouse balls to make the eye balls.
Doing it this way i can make 'one' eye then simply 'move' the eye ball left or right or to the middle before copying in foil then PM strips (Paper Mache). I do need to flip the eye 'ridge' over left/right of course but thats no trouble.
