"Missed hole technique" is confusing. As usually employed it
applies to leaving 1 or 2 holes empty in a warp-twined structure, leading to
diagonal or transverse grooves. So they produce three and two strand warp-twined
structures. I think the word "missed" came to be used because you
normally use all four holes in warp-twined TW.
But there are many other
structures produced by NOT using all four holes (see sections, I, N and O in
Classified Threading Techniques, which is Appendix One in TTW) These are of
course technically missed hole, but I describe them as "Two threads per
Tablet".as they give new structures which are not
derivatives of 4 thread-per-tablet structures.
This is in that dangerous field where you
have to be so careful that you distinguish technique (method) from resulting
structure. An accurate description of a band should include both. For
instance, "Three-strand warp twining produced by missed hole technique"; "
3/1 Broken twill, produced with two threads per tablet".
The desire for snappy short titles can lead
to these two aspects getting muddled.
