The board is created to show how long the earrings you have made are. If you'r making earrings on your own you don't want to try them by yourself so this is made with a Ear in average size for a mid year woman in mind.
This is designed for earring hooks. If you want to try with studs, you need to make the circle on the ear bit smaller.
RED = Cut
GREEN = Engrave
VIOLET = Score
For me I want to be able to easily transport it, thats why I use some tape on the backside to held in place. If you don't need it use some glue to make it permanently.
Now you can hang you earrings and show off how long them are.
