WeaveMaker User's Manual — Threading Catalog
Threading and treadling schemes are no different, aside from which grid they work within. The examples given here are all for threadings, but turned sideways they are equally valid as treadlings.

The Network scheme gives threadings (or treadlings) which are straight draws which (a) do not cross all harnesses and (b) systematically shift their starting harness number (see illustrations below).

Used in place of a traditional straight draw in a twill, the effect is to give complex twill-like structures (see below).

Step Walk
The Step Walk scheme gives threadings (or treadlings) which are modified point draws (see illustrative threadings and sample fabric designs below). The threading consists of straight draws in alternating directions, with widely varying draw lengths. Unless you constrain them with a marquee, step walk threadings do not have natural repeats.

The ZigZag scheme gives threadings (or treadlings) consisting of short straight draws of unequal, but systematic, length (see examples below). They can have a natural repeat. A wide range of fabric designs are possible with this scheme (see below).

Stutter Twill
The Stutter Twill scheme gives threadings (or treadlings) consisting of normal point draws, except that they have hiccups (see examples below). The effect of this is to give a slow variation in the pattern across the fabric. The illustrations here show this effect across the warp. The amount of variation across the fabric is different each time you invoke the scheme; try it several times to get exactly the effect you want.
