The roll is stopped! I had a couple of potential solutions in mind when I ripped back. I had a bit of yarn left, and did a few practice swatches. Which is a good thing, because the stitch pattern I thought would be the best one did not look good at all. Yay for swatching! Then I messed around with a couple different bind offs that i thought might look cool, but none of them was quite what I was looking for.
What I wound up doing was a couple repeats of the same pattern as on the bottom to give the top edge some structure, and then just a plain old traditional bind off. Whew!
Now to finish nerd-wrestling with the pattern! Meanwhile, here is a close up.
Side issue – what should I call this thing? I have been thinking of it as Dissipation or Dilution, but those aren’t quite right. Any ideas?
