In my opinion, this pattern may be in some ways easier than the pattern previously outlined. For one, more satisfying and pleasing results may be obtained. Furthermore, the pattern is also slightly easier to control. This method is also a good way of approximating the old combed patterns that you see in old books.1- lay on the trough a base colour, usually red.
2- on this , lay droplets of black (K), blue ( B) and yellow( Y ), in a grid fashion, as shown below
Y B Y B Y B Y B
K Y K Y K Y K Y
Y B Y B Y B Y B
K Y K Y K Y K Y
( obviously, you can adjust the number of rows & columns to the size of your trough)
3- Stylus through the vertical columns, & comb across them.
=> obviously, you could use different colours from the above- Those colours are simply the most traditional.
This method of making nonpareils has long, orderly bands of colour, instead of the shorter, random stripes of the previous method. Whilst this produces a more symmetrical pattern, it may look a bit too mechanical, if you are not careful.
If you substitute blue for green, you get a pattern known as the "old dutch"- However, I actually know of three methods of making a pattern by this moniker, and so, I have included it in a seperate post.
