Stained glass lattice coloring page
A lattice of diamond panes, each with a smaller diamond set inside it, the pattern used in leaded windows long before colored glass was common. Real glass is strongest in a few glowing colors, not many. Pick three or four and repeat them around the window, and keep the leading between the pieces dark.
Fine lines, patterns and many small areas for colored pencils and markers.
