Altering Cyanotype Prints

This is a repost from October 2021 when we attended a Red Thread Retreat with Lesley Riley to learn more about cyanotype/botanical printing.  

At the Red Thread Retreat, we enjoyed learning ways to alter our cyanotype images by using different chemicals and techniques. Serendipity is also a big part of the process. Even though you change things up from a traditional blue and white cyanotype print, you never know what you will get when you start adding other components to the experiment.  There is a lot you also don't have control over such as the amount of sunshine, the humidity and the angle of the sun.  You can somewhat control other additives to the botanicals placed in your design.



To end up with the image above, a piece of watercolor paper which had been treated with the Jacquard Cyanotype chemicals was used. Once the botanicals were added some turmeric and then Ferrous Sulfate was sprinkled around the edges of the plants.  The very interesting results on the left of the paper was from a leaf that had many holes in it having fallen on a gravel parking lot and been run over by cars.  The piece was also lightly misted with a vinegar and water solution.


For an October day we were fortunate to have warm temperatures hoovering in the high 70s to 81 with lots of sunshine so the paper. with plants and chemicals incased under a piece of glass, sat out in the sunshine of the parking area for at least half a day to "cook".


When the botanical materials were removed, the image looked like this but it still needed rinsing off in cool water to remove all the chemicals.  Before rinsing it looked like this:


The development process can still continue for a day or so, the final image looks like this now.  It might get cut up to put into a new collage and likely that geode looking area on the left will be a highlight of a new piece.

Cyanotype Experiments on Fabric

To continue with cyanotype, Sue decided to make some fabric prints last week and try a little experimenting.  Nothing outlandish, just some simple additions.  Her usual go to for altering backgrounds is to spritz with water and a soda ash solution.  This time the solution must have been pretty strong (or the chemical coating for the cyanotype was thin) Because it worked almost like bleach and completely took out the color in places.  Or maybe she was too heavy handed with the spray?


Above are the 2 pieces set out in the sun.  The places that appear yellow in the photos are where the soda ash solution was sprayed.  The brownish spots are sprinkles (or clumps) of turmeric.  


These are the 2 pieces after a few hours in the sun, before removing the glass and plant material.  The plants, by the way, are a mixture of ferns, nandina leaves, money plant seed pods, and an unopened blossom from the nandina.  


Here's what they look like after removing the plant material but before rinsing. It takes several rinses in cool water to rinse out the cyanotype solution.  Continue rinsing until water runs clear.  Usually, Sue lets them soak overnight.


Above are the two prints after rinsing.  You can see in the one on the right how the soda ash solution took out the blue background instead of just giving it some texture.  The gold-brown spots are from the turmeric.  Overall, both pieces turned out well.  Note to self, go easy on the spray next time!  And perhaps some more experiments with other substances to come.  Looks like we're in for some sunny, hot weather this week.

SAQA Benefit Auction

Each fall, Studio Art Quilt Associates (SAQA) holds an art quilt auction as its main fund-raising event. Proceeds support exhibitions, publications, and educational outreach. Twelve-inch square quilts are made and donated by members and then auctioned in an online event over a period of 3 weeks in September/October.  Sue recently completed and sent in her donation.

"Filtered" was made from scraps of shibori/indigo and rusted fabrics along with a cyanotype printed on a flattened coffee filter.  Both hand and machine stitching were used to quilt and embellish.


Here is the background prior to adding the cyanotype where you can see the various fabrics used, all leftovers from previous projects.


Portions were quilted with straight line machine stitching.  Other parts were enhanced with hand stitching.


Above you can see some of the hand stitched circles and a row of fly stitches across the bottom. You can also see the machine stitching that outlines the cyanotype print and a blanket stitch used around the edge.


Here is the backing with corner triangles for hanging, or alternatively a ribbon loop in the center.


And the finished piece.  Watch this blog and our other social media for notice when the auction takes place this fall.  Bidding is open to anyone.  There are always many fabulous pieces of quilt art available.
