I test the folded papercut periodically against a contrasting background until I am satisfied. Next, I design slightly smaller oval shapes on tracing paper with a felt pen or a fine magic marker. These are for the overlays of color, to be contained within the design. I cut three or four colors at once and try these in various combinations. They will be used in progressively reduced form.
Some accents are scallops, some saw teeth, and some with fringe like feathering.
Be sure to include in your palette of colored overlays, sharp yellow, magenta, turquoise, emerald, and chartreuse. Violet, red, and orange will give an extra sparkle. The colored overlays not only give richness to the Lowicz style medallions but also an extended sense of dimension and luminosity. It is a great temptation to use origami paper because it is so colorful and easy to cut. Unfortunately, the colors fade when exposed to light over a long period.
