I painted this tree with a crumbled up piece of printer paper. The type and size of paper can prouduce unique textures.
I should have used emerald green or white instead of kraft paper. Pressing down lightly or heavy also gives even more interesting textures.
Here’s another tree I made with a heavy cardbard that I cut and bunched up into a ball. This tree didn’t make the Wise Trees but I do like the texture. In both these designs my crumbled up paper was about the size of a quarter. To really get a good texture you probably need a tennis ball size.
