This past week I invited two friends over to learn how to rust dye fabric. We used rusted wire, motorcycle sprockets, nails and something square. First wet the fabric with water, then spray with a mixture of vinegar and water. Wait at least 24 hours for the rusting magic to occur.
Four Squares a Day
This fabric is called Foggy Mornings. It was created by rusting and then adding tea (tannin) to the iron oxide . This created a mordant that turned the fabric black. It was like doing a chemistry experiment.
