In some sources, opposites refers to pattern blocks. As, for example, Harriet
Tidball's diagram of Cottage Windows. It's treadled . . .
Treadling pattern is in the right-hand column. |
One pattern block is treadled with shafts 2-3 for so many weft shots, and then treadled 1-2 for so many weft shots. The second block is treadled with the opposite shafts 4-1 and 3-4. With this treadling, tabby must be used, or as you can see by studying the treadling sequence, the common shaft in 2-3 and 1-2 (shaft 2) would always be lifted and create a long warp float over the top of the fabric. Ditto for shaft 4 in the 4-1 and 3-4 sequence. Tabby is needed to tie these down to the fabric.
The second definition defines opposites as alternate sheds, using contrasting
colors for the wefts. One weft shot of shafts 1-2 is alternated with 3-4.
Tabby weft is optional, but said to make a more stable fabric.
My
Cottage Windows table runner
is an example of the first definition, opposite pattern blocks. One of these
days I'm going to have to rustle up a pattern using the other definition,
opposite sheds. It will be fun to experiment.
