Here's a closer picture
of plants being arranged on fabric. The pot in the forefront contains copper sulfate which Pat makes by soaking bits of copper in vinegar. We used some of that to presoak our fabrics.
Here are some of Pat's fabrics hanging on the line afterwards.
Below is a photo of two fabrics I printed at her house, the one on the left was prerusted and the other not. You can see that when you add iron (in this case in the form of rust), the prints are darker. It does also depend on which plants you use.
Here's a photo below of a silk scarf that I printed. I used a lot of coreopsis and that made it so yellow with orange. The pink leaves were eucalyptus which I had bought at the florist. The blue/black is buckthorn berries. Thanks for stopping by to have a look!
