This design is a based on a band I wove back in 2011 (the black and white one in the picture above) to use up the last of the long-discontinued acrylic crochet thread I learned to tablet weave with. I set up a warp to weave two thread wide diagonal lines and improvised the design, changing the turning direction of pairs of tablets in a technique often known as Egyptian Diagonals (despite it being extremely doubtful that it has any historical link to Egypt). I had been planning to share it with you unedited, but when I came to draft it out in TDD, I found a number of odd decisions that could be improved on. The new version I'm sharing here has two more pattern tablets and 2 more picks, retaining the twist-neutral design of the original, while making it make rather more sense.
Counterchanged is a term used in heraldry to mean that two colours have switched position on either side of a dividing line, the motif colour becoming the background colour and vice versa. In combination with the weaving technique, it comes together to make a pretty fun design. The yarns I used in the sample band were King Cole Merino-Blend 4-ply in the colours black, blackcurrant, sapphire, grass, mustard, cinnamon and red, with black as the weft, the same as my Rainbow Triangles band.
If you would prefer a shorter turning sequence, repeating only the first 24 picks will give you just the simple rainbow diamonds and repeating only picks 25-48 will give you just diamonds on the background of diagonal lines.
