Grab a few coffee filters and color them completely with washable markers. I used fall colors like orange, red, yellow, orange and green.
Take a spray bottle filled with water and spray the coffee filter until its completely wet but not soaking. Try not to wet it too much otherwise the color will run a lot but if your little one does it ok! I encourage my kids to color in several coffee filters so they have a bunch to spray.
Set it aside to dry.
Cut out the outline of a tree with branches from black construction paper. Or print out the tree template below and use it as a guide to cut out the outline of tree from black construction paper. (Alternatively, you can cut out a trunk and branches separately and invite your child to design and glue them to the coffee filter in the shape of a tree.)
Once the coffee filter is dry, glue the black tree outline to the coffee filter.
Display you tree craft on a window using double sided tape.
