If you have earrings that are starting to wear on the edges
use a Sharpie to cover up the worn places.
I have also used a Sharpie to cover up scratches on my husband's dress shoes.
I have used a Sharpie to cover up scratches on picture frames...
The ways to use a Sharpie for repair are almost endless.
Use what ever color of Sharpie to match what ever you are trying to fix.
Do you have other ideas or ways that you use a Sharpie for repairs?
