This fabric sat overnight with vinegar and various sized rusty nuts and bolts. They came from our neighbor who is refurbishing a boat and who knows I'll take anything rusty. The result is the puppy dog front and center in my Rust-dyed Critter Gallery (second photo). I'm giving this one to my neighbor because it wouldn't exist without his help, and he has a very sweet Goldendoodle. I even embellished it with scraps of curly mohair left over from my ongoing teddy bear project. It reminds me of his curly fur.
