I’ve bought a number of Procion MX dyes lately, from both Dharma Trading and ProChemical, and decided to do some small samples. I soaked a narrow strip of fabric in soda ash and let it dry. Then I cut it down into small squares, about 1 1/2 x 1 1/2 “.

I keep them in a notebook, along with other samples I’ve done. The amount of dye used was very haphazard, and I’m sure there was too much dye in several cases. But it has proved to be a good reference. Here are my results:
