Knitting a spiral in the round seemed a good idea when it first appeared. I forget that it’s possible to knit in both directions while knitting a tube, so it might work. Using yarn from both ends of the grey, with the rainbow stuff in the middle. Nice reminder of how the ink looked on a zinc lithography plate before printing.
I’ve knitted a lot of hats. They disappear when needed. I thought the family cyclist should have a bright hat for any smidsy moments. The neon orange yarn I bought in the 1980s would be too painful alone, so pairing it with black stripes might be better. There again, a spiral could be interesting…
Black and orange spiralling
The Maths for this is easy in theory, moving each colour over by one stitch on every row. In practice I’ve had to stop and think occasionally. Knitting in the round usually involves spiralling upward, rather than the to & fro of two needles. This time, I have to remember to slip the first stitch of the colour, then pick it up on the return journey. There are obviously other methods but this is ok for the moment.
