BluePrints are a learning experience.

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!
