Rust dyeing is something I wanted to do for a long time, but there was noting rusty to find. I asked my husband to save his rusty bits and last week he gave me 2 rusty screws. Now I could do my first experiment! I used a scrap of embroidery linen, soaked it in a mix of water and vinegar and wrapped it around the screws. After 2 days I rinsed it in water and washed it. Next time I need to secure the edge first!
