Shrinking Your Draft – Point Twill and more
So now that we did the straight twill draft in the last post, what about a more complicated draft? Let’s go through the same steps with point twill:
Originally the draft called for:
-
- 42 ends of each of 20 colors for a total of 840 ends
- sett at 24 epi: this is 35.1” wide in the reed
- Here is a draft showing the 4-shaft point twill for two colors, 42 ends of each color:
Step 1: Knowing what you have.
- the ends per inch (epi)
- the width of the original project
- the total number of ends in the original draft
Then, determine the maximum number of ends in the smaller project.
- How wide is the weaving width of your loom (the width of the reed)
- Multiply the width of your loom by the desired ends per inch (epi)
On the Baby Wolf loom:
- Baby wolf loom has a maximum weaving width of 26”
- At 24 ends per inch, the maximum number of ends = 624 (24 ends per inch X 26” wide = 624 warp ends)
- And using 20 colors in the warp you can have a maximum of 31.2 ends per color (624 ends / 20 colors = 31.2).
Step 2 is to look at your draft and determine the repeat in the threading.
For a 4-shaft point twill: 1,2,3,4,3,2 the repeat is 6 threads.
Step 3 is dividing the number of available ends by the threading repeat.
Returning to our Baby Wolf Gamp project:
-
- We have established in Step 1 that you have a maximum of 31.2 ends per color to work with.
- For a 4-shaft point twill (6 thread repeat from Step 2): 30 ends of each color would work. 30 is divisible by 6, giving you 5 sets of 1,2,3,4,3,2 point twill, for a grand total of 600 ends at 25” wide.
- Here is the modified draft for two colors showing 7 repeats of the threading unit for each of two colors.
If you now understand that…how about these:

Thank you for the information. I have seen many patterns I would like to do but require a wider width. Now I can try those patterns.
This information is especially useful for beginning and advancing weavers. Thank you for including it in this post.
