Here's another idea for a Thank You note that is quite easy to do . . .
After stamping the background leaves with VersaMark, I waited until the watermark effect showed up when the clear ink turned the paper darker and the leaf became more visible. Then I lightly colored in the open spaces of the leaves with the Prisma White pencil. The effect is subtle, adds visual texture, and doesn't compete with the focal points.
