Faded burlap, like the sacks potatoes come in, not the marine sergeant.
Gunny Sack is a pale grey, close to beige.
It can be described as pale, delicate, faded and almost grey.
Set in black, because black reads best on it.
A gunny sack, also known as a gunny shoe, burlap sack, hessian sack or tow sack, is a large sack, traditionally made of burlap formed from jute, hemp, sisal, or other natural fibres, usually in the crude spun form of tow. Modern-day versions of these sacks are often made from synthetic fabrics, such as polypropylene.
