You can get graph paper in all different shapes, not just squares. I know there is triangular (2 triangles make a diamond) and there may be a diamond shape as well. You can find them on line. Do a search for graph paper. You can also buy pads of graph paper in office supply and art supply stores. Once you have the paper, you can grab your color pencils and design away! :D
