Flatten your coffee filters and color them using watercolor paints or markers. Try blending colors like turquoise, purple, yellow, and red for a bold effect.
Lightly mist the filters with water to help the colors flow together, then let them dry completely.
Once dry, cut the filters into semicircle shapes for bird bodies. You can get about two birds per filter.
Cut small triangles from colored paper for beaks and half-moon shapes for wings.
Glue the wings and beaks onto each semicircle, layering pieces to give every bird a unique look.
Arrange your colorful birds in a frame, on cardstock, or along a wall. They look best grouped together like a rainbow flock frozen mid-song.
