So, with fabric prepared, I picked some day lily dead heads from a browny/maroony/orangey lily. I boiled them and filtered the plant material. I put pieces of all three mordanted fabrics (A, B and C) into the liquid. Maybe a cup of liquid. And each piece of fabric was about 4″ x 4″.
As the fabric sat in the fabric, it was getting darker and darker. What excitement. Looked maroon/purple to me. WAHOO!!
BUT, as it dried, it was really more grey. Maybe a hint of blue.
