Here's how to do it:
Select a color scheme. We talked about analogous colors (colors next to each other on the color wheel), but warm or cool colors work nicely too. They then painted a light watercolor wash on white paper. Leaves, that each student brought to class, were then placed on top of the watercolor wash - veins up. Then they took darker paint colors and painted the edges of the leaves -making sure to overlap the darker color onto the paper. This was left to dry overnight. By the next morning the leaves had absorbed the paint and in the process, left a "print" behind.
Leaves absorbing the paint
Finished painting- the finished paintings look great by themselves OR, they would be an awesome paper choice for future collages.
All the leaves after we peeled them off our papers. How cool do they look? I wish I would have gone straight to the laminator and preserved them -but I was nervous about jamming the laminator (been there, done that).
