I worked from the Quilt Rat's recipe although I did use washing soda. My internet research suggested that soda ash and washing soda only differ in their moisture content so I compensated for that in my mixture.
I did make the solution over 3 weeks ago but household responsibilities prevented my playing with my toys for a while.
So, last night I soaked my pieces of bleached muslin and a white cotton. I dried them on a wooden rack overnight. They were pretty crusty so I used a towel to brush off the dried crystals and then ironed the pieces flat. Next, they were pressed onto freezer paper and cut into the paper size I need for my printer.
I had prepared a few photos so that they were close to 4" x 6" and 300 dpi. I printed these at the best photo print setting that I have. Of course I did have to trick the printer into taking the paper. It did not believe that I was using premium quality glossy photo paper; I found that a matte paper setting worked.
Here are the pieces:

Come back in a few days when I have rinsed and embellished these prints. I am experimenting!
