Fun With the Sun

Cyanotypes, which are actually photographs, are yet another way to create designs on fabric. A cyanotype “is a photographic printing process that produces a cyan-blue print. Engineers used the process well into the 20th century as a simple and low-cost process to produce copies of drawings, referred to as blueprints. The process uses two chemicals: ferric ammonium citrate and potassium ferricyanide.”

You can coat fabric with those chemicals yourself or you can buy fabric already coated. After that, the process is the same. You choose materials you want to photograph and lay them on the treated fabric.

Then, you cover them with glass or some other clear object to hold the materials in place and expose the fabric to the sun for 10 to 15 minutes.

After you bring the fabric inside you remove the materials and rinse the fabric in water. Then you admire your results.

I had bought a packet of assorted color pretreated cyanotype fabric squares with a gift certificate from Dharma Trading, and was waiting for sunshine and warm weather. When those events aligned I set up my work area on the roof of my screen porch.  Why the roof? Because I can access it through a door from my bedroom. I suppose the people we bought our house from had visions of night star gazing, but it’s three stories up from the driveway and the railing isn’t very high. Also, wasps love to build nests on the railing. So I was happy to find a use for that roof.

I was pleased with my results, and have found many breathtaking examples of this technique online. How about this delicate piece by Linda Sterner?

I have no idea what I’ll make with my crocheted pieces, but I still have eight more treated fabric squares to play with.
