The 40 pages of eclectic fantasy art contains everything from dragons and unicorns to fairies and mermaids and few surprises in between. They are printed on one side only. The variety of art will set your coloring imagination free. So choose your colors and method and let your creativity guide you. My personal favorite is artist grade colored pencils. But you can use magic markers and crayons. Wet media, like watercolors, acrylic paints are not recommended.
