Cyanotype Blueprints

When Boo and I were making our pinhole camera I wanted to teach her how 35mm film worked.  I gave her this pack of cyanotype fabric and let her decide what to use from around the house to make her prints. Cyanotype is what they used to reproduce blueprints and diagrams a hundred years ago or more……those pretty architectural type drawings you wish you’d find in a thrift store one day (or at least I’m always looking for them!)? Cyanotype is basically a photographic printing process that results in a blue or “cyan” print.

It’s been about 25 years since I’ve used sun printing paper but it’s something I’ve been thinking about for a while! Who knew there was sun printing fabric?! I made this easy little square pin cushion using 8.5″ cotton cyanotype fabric squares and buttons:

 

This applique shirt was so simple…


…and I love the extra button detail:

 

 

The squares I used are the Blueprints on Fabric(pink on blue) shown below:


In a nutshell, the 8.5″ fabric squares in the kit are pretreated with a chemical that makes them change color in sunlight. I took the squares and pinned them to cardboard backing to keep them in place and laid various objects on top to experiment:


I placed the board in the sun for about 10 minutes and let the sunlight do its thing. The fabric darkens slightly (not to its dark blue you would expect):


Once the fabric has been in the sun for about 10 to 15 minutes, it is washed with cold water and the dark blue color appears:


I’m pretty sure there are over million things you could do with this fabric…here was my first hour of playing with it:

 

I pinned buttons to the fabric in the shape of a heart:


I pinned one of my mother’s old necklaces in place:


I layered different types of lace:


I used a transparency with a superhero “POW” on it:


Stay tuned for more sun printing soon!
