Hammering: Natural Fabric Dye

This is a really cool fabric dyeing technique that I learned when I was younger.
It's surprisingly simple: all you need is a hammer, some fabric, a flat surface, and some plants.
Well, and something to fix the dye helps.

Paper towels are a good material for this. This will help protect your surface from plant colors.

Ferns and green things work best.

Securely.

Soak it in a salt bath!
I'm not actually sure how effective this is.
