In my last post (Summer & Winter: A Basic Definition), several threading characteristics were mentioned. While threading alone does not make the weave what it is, it is still a very important part of it.
Summer & winter is a unit weave. Threading units consist of the least number of threads necessary to define a weave. For summer & winter, each threading unit must:
- Have four warp ends which:
- Include both tie-down ends
- Use only one of the pattern ends
- Alternate tie-down and pattern ends
More shafts would give us more units:
Etc. Designing comes in deciding which units to use, and how many times to repeat them.
As you can see, the number of units we can use depends upon the number of shafts we have available. I can have two less units than I have shafts. In the example above, shafts 1 and 2 are being used for the tie-down ends leaving shafts 3 through 8 to make the pattern. To use all eight units, I would need a 10-shaft loom.
One thing that units lend themselves to, is profile drafts, which I've attempted to explain in a separate post, here.
