Printed on fine-quality, translucent sheets, sixteen different bird species await your creative combination of colors. Boldly outlined flyers feature such popular breeds as the blue jay, northern cardinal, swallow, and robin. Six double-tipped markers are included, but you can also use crayons, watercolors, pastels, or colored pencils. When the coloring fun is done, tape the sheets to a window or hold them up to other light sources for cool stained glass effects
