Today our series of marbling pattern tutorials brings us to the nonpareil pattern, from the French "without equal". Though truly the nonpareil is not one of my favorites, it is a step towards some further compound patterns whose elegant line quality depend on it. This pattern requires a nonpareil comb, whose tines have 1/8" or 1/4" spacing - but if, like me, you don't have such a comb you may carefully use a stylus. This gives a looser, less static quality to the pattern.
Complete a getgel pattern (at left above), then draw a series of tightly spaced parallel lines perpendicular to it.
The nonpareil pattern begins with a getgel, which may be repeated once or twice for finer lines. Remember before beginning to make a note of your paper grain direction, and do some strategizing so that the completed pattern will be oriented as you wish.
Working perpendicular to the existing pattern, pass your nonpareil comb through the pattern once or draw a series of closely spaced lines with a stylus.
I did not pull a print of this pattern, but continued working on it. However, below are some lovely vintage examples of the nonpareil from the digital collection of the libraries of the University of Washington, which also illustrate the effect of pattern orientation.
