With this draft I am not weaving tabby, but if I were, I would treadle 1 Vs. 2+3. All the pattern shafts Vs. the two tie-downs.
But since I am weaving 'on opposites' I do not want to weave tabby. If I want a solid row of background texture, I will weave these treadles:
2 = tie-down one
1+2 = tie-down one, and all pattern shafts
3 = tie-down two
1+3 = tie-down two, and all pattern shafts
I will repeat for a total of 8 picks. Yes, I am stepping on two treadles at the same time.
If you look real close it is different than tabby. Tabby is over one and under one. This is BACKGROUND texture.
