This is a recent piece of compost dyed fabric, it's cotton, found it on the end of my table underneath everything. I've decided I need to stitch this piece, I see all sorts of wonderful natural things in it's surface. I might add some other fabrics with if I ever find my pile of compost dyed fabrics. I've found my pile of solid/mottled natural dyed cotton fabrics, but not my compost dyed ones. You know it's a good thing that the Good Lord had the sense to attach my head or I would have lost it decades ago.
