Solar Dyeing Experiments

I've been experimenting with solar dyeing -- using the heat and energy of the sun to dye fabrics rather than boiling or simmering them using electricity or gas.

Lots of yellows in this batch of pomegranate rind, yellow dock root, and juniper berries:

Some materials work really well with solar dyeing, like this batch of pomegranate rind with a little copper added from an oxidized copper pipe:

Other materials don't work well, like these carrot tops which don't appear to be emitting any color at all:

Thus the need for experimentation!
