I purchased the kit located here: Hue Shift Afghan

Since there were so many warnings in the reviews at Knitpicks about the estimated yardage being a little bit tight & the possibility of running out, I ordered an extra skein of each color in advance, just to be on the safe side.

ETA: Ultimately, I had some colors that needed the extra ball, and others that were just fine. I don’t know if this was down to gauge or some other reason, but I may use the leftovers to make a second afghan in a slightly smaller size.
