I decided I wanted to make a Noro Silk Garden sweater in one long gradient, which meant combining balls of yarn by breaking them at the color changes. It was an interesting experiment...
Here's what four balls of yarn, split into colors with all like-colors piled together, looks like:
Overall, I split apart 10.5 balls of yarn, and I had less than one (of pieces) left over when I was done. I made up a pattern, explained more on the Ravelry project page.
The chevrons transition into the Carillon pattern nicely... centers and edges of the chevrons lining up with the "bell ropes."
