Smitten! Who knew all that red was inside? Fortunately for me, the yarn has been discontinued.
A few weeks later I found wandering single balls of two different yarns. One was a little thicker and a little fuzzier. I decided to see if they would work together. So I cast on with the thicker one and ribbed until it ran out, then joined the other ball. It turns out that the thin stripe of blue after the first whitish section was a perfect match for one of the blues in the second yarn, making the whole thing look totally intentional:

The pattern: 100 g worsted weight yarn. Cast on 96 stitches on whatever needle size you like for worsted . Knit 2, purl 2 for 11 or 12 inches. Work 6- or 8-point decreases, as you wish, staying in pattern as much as you can.
