Once the leaves were collected, Janis pressed them in a phone book. To use for printing, the leaves still need to be soft and flexible. So the pressing is only for a few hours or overnight.
First, each student chose a few leaves, and then put a small amount of 3 colors (tube watercolor) on their palette.
They arranged their leaves on the watercolor paper, paying attention to the composition. Positive and negative space was discussed- the artists were to look at both as they decided where each leaf would be placed.
After painting the back side of a leaf with one or more colors, they pressed it down on their paper, using a folded paper towel on top of it-to make sure they didn't tear the leaf.
