This is one of my favourite methods for eco-printing on paper. The rust from the metal can helps you to get good results from pretty much any type of leaf or paper. If your paper gets crinkled or uneven from the dyeing process, you can flatten it again by ironing it on a low setting. Either while the paper is still wet, or after lightly misting it with water. If you have any questions about the process, please ask me in the comments below. I love helping people have success with this beautiful and magical process. I have more eco-printing tutorials on my website, www.gumnutmagic.com And there you can also find my range of ebooks with step-by-step instructions to eco-printing on paper and cotton.
