I will keep thinking about single two-tie but now I am going to weave some shadow weave. This is from a kit. I sometimes will weave other peoples stuff and try to understand what I am doing. Shadow weave may be to spacial for me..... but I will give it a go.
Two colors in the warp and weft. And I understand it is very important that you know what color you start with in the threading and the treadling. It really does create a complicated looking pattern, and only on four shafts!
I have wound my black and blue threads separately and threaded the black first then laid the blue on top and pulled it through the reed. This is when that 'cross holder' comes in very handy!
