This is todays attempt. I have found several issues that come with the types of material that you use. I switched from the lower end cotton material that I first used to a looser weave fabric in hopes of better absorption of the material and less bleed. Bad idea! What happened was a complete separation of the chemicals through a wicking like process resulting in the second image below. The higher quality material that I got after that failure resulted in a much better quality image but still has some bleed/wicking issues. The first image is the result of my days work. Not too bad but a little overexposed. I had some significant issues with controlling the exposure times as a result of the changing sun. There is a significant difference in exposure times between an overcast and sunny day as well as a 10am sun and noon time sun. The test strip that I did at 10am was vastly different than the results I was getting at 11am!
Secondly I had saved the leftover mixed solution and used in on some fabric today. It acted fine to my eye. It was only a couple days old but is nice to see that storage in a brown bottle will result in the leftovers not being wasted and able to be used a few days later.
Overall a great learning process for today. Enjoy!
