Sometimes you might want to have a certain number of warp threads threading in one direction, say in the S direction (with the slant going / ) and then a certain number of threads in the Z direction (opposite direction), and to repeat them over and over for a threading draft. You do not need to have a multiple of 4 threads for 4 shafts or 8 threads for 8 shafts, etc. Say, you want to have 6 threads going S, and then, 12 going Z and reversing (or making a point) after each number of threads. The threading would be 6 threads in the S direction, 12 threads in the Z direction, then, 6 in S and 12 in Z for as wide as your draft (or cloth).

Using the twill circle can help you greatly. Make a circle with as many points on it as shafts you are planning to use. For 4 shafts, number the points 1,2,3,4 as shown in the illustration. Now, working clockwise on the circle and also on your threading draft, begin with 1,2,3,4, and repeat the numbers until 6 threads are indicated on the threading draft. You’ll stop at shaft 2: 1,2,3,4,1,2. Next, reverse the direction of the threading (make a point and reverse directions), and work counterclockwise on the circle. You’ll stop at shaft 3: 1,4,3,2,1,4,3,2,1,4,3 for 12 threads. Since the point thread “goes with” both directions, count it as a thread in each direction. (Note that for the 12 threads, the 2 from the first set of threads is counted as thread number 1, and there are only 11 new threads written in.)
The circle can be helpful in making a treadling draft as well. I find it quite useful when I’m drafting twills, and at other times, too.

A special kind of point
There’s another kind of point that is nice to know about because sometimes the regular point discussed above can look a little odd at the tip. It just isn’t crisp or sharp because of the floats of threads. If this phenomenon happens with point twills, beat the wefts at the points more gently than usual to avoid the wefts from packing in too close together there.
A broken point can solve the problem and create very sharp points. Again it can be used in either threading or treadling drafts, or both. At the point, there is a “hitch” in the threading. To find out how to make the hitch, use the twill circle. When you have enough threads going in on direction (S or Z), go directly across the circle and begin going in the opposite direction with that number. In the illustration with 4 shafts, if you stopped at shaft 3, working clockwise, you would go across the circle to shaft 1 and work counterclockwise to determine the threading or treadling.
This illustration shows a twill circle for 8 shafts. If you had stopped at shaft 5, the next shaft to use for a broken point would be shaft 1. If the last shaft before the direction change were 7, the next shaft would be 3.

This illustration shows a broken point threading on 8 shafts.
