After thanking the Media Lab's dark room's staff, I was able to dowse the picnic blankets (constructed by me with fabric also thanks to the Media Lab) in cyanotype solution and let them dry in the room overnight. Kept them in the room for storage depending on the day when the weather was appropriate, I began to invite friends onto these picnic hangouts with me. They were more than excited to sit on a chemically induced blanket.
And so the picnic blankets became alive. They each hold a 30- minute memory, each with a different weather, different people, and different events. The only thing that remained constant was the location. I chose a spot that was partially covered by a tree shade in the change to see if the shade from the tree would show through. It did not.
