Inspired by leaves on the street on a blustery day, I captured a few by chasing them down the street pushed along by hefty gusts of wind. Must have looked a fool, but I got some good leaves.
Rather than press them or cover them to keep them fresh, I went straight for my dye pot and cut up some watercolor paper and started stacking. The usual mix of water and some big glugs of white vinegar in the pot. I put a tile on the top and one on the bottom of the stack of papers and leaves, and left them for almost 2 hours simmering on the stove with a couple rocks on top to hold them down and keep them flat.
Here they are the following day. I took them out of the pot after the allotted time, and set them on aluminum foil to set the color better, leaving them overnight.
Next morning this is what I found as I opened them up.
