On Friday the 13th, I demonstrated rust dyeing at the "Sampler", one of the events at the International Quilt Festival in Chicago . I placed a rusty star on a styrofoam plate, added a bit of salt and a bit of water, then I showed some other techniques from the Rust-Tex Instructional CD. After each demo I put the plates on top of each other. At the end of the event I put the whole pile in a plastic "zip-lock" bag.
Today at home I opened the bag,
unpiled the plates,
rinsed the fabric and hung the newest batch of stars on the line to dry. As I scrubbed each plate to reclaim the rust dust, I was surprised to see the stars had made marks on the bottom of the plates.
Would rust dyeing work on tyvek?
