How about two colors? I am still using the 10/2 cotton, and think they need to be a bit thicker, but for now I am just concentrating on the color combination. I started with red, but what would it look like if I started with the blue? Again, I have shown one repeat of the treadling with the beginning and ending edges.
And how about those edges? Well, I did not try to carry the color up the side like I would if this wasn't a sample. But the eight threads on each side in 1-2-3-4 order has allowed me not to use a floating selvage. And remember, this will look a lot better once it is washed and ironed.
