CREATE COLORFUL PAPER: Use tempera paint sticks to cover one piece of paper with colors, lines and designs. Fill as much of the white space as possible.
CREATE THE BACKGROUND: Paint a second piece of paper with one or two watercolor colors, or use construction paper for an easier option.
LET THE PAPER DRY: Allow any wet materials to dry completely before starting the collage.
TEAR LONG PAPER STRIPS: Tear the colorful paper into long strips. Smaller pieces can also be used to fill in the tree.
ARRANGE AND GLUE: Arrange the torn strips into a Christmas tree shape and glue each piece in place.
ADD DETAILS: Add a star, trunk, ornaments, collage materials or marker designs to decorate the tree.
ADD SNOW, OPTIONAL: Thin white tempera paint with a little water and splatter it over the finished collage with an old paintbrush or toothbrush.
