When they picked up the paste paper from the scrap sheet, it was apparent to me that they had also made prints! The dye from the paper was quite fugitive and left interesting marks.
I took out another black scrap and played around, aiming for the marks left behind on the scrap paper.
I eventually ended up tinting one with the tea I was drinking and pasting down the black paper on the other for a collage. I wish I could have gotten better photos, but so be it.
