Grayscale pencil sketch coloring means that you will be coloring over a black-and-white pencil sketched picture. The vintage images have been digitally altered to create a realistic pencil texture that shows through after coloring. Colored pencils work beautifully with the grayscale pencil sketches giving the finished picture depth and dimension. The images are printed on only one side of the page and the paper is well suited for colored pencils. If you use markers put a sheet of paper under the page in case of bleed-through. Features: 101 pencil sketch coloring pages. 8" X 10" white paper. Printed on one side only. A place for the colorists name and date.
