This is an advanced-level (or maybe adventurous intermediate) cable motif 52 rows high, that starts and ends with 19 stitches. It assumes knowledge of basic cables, and uses a number of cabling techniques in slightly non-standard ways. It has been charted to be knit back-and-forth, but should also be possible to knit in the round. Besides your chosen yarn and needles, you will need a cable needle, unless you like to knit cables without one.

In addition to the cabling, there are k2tog and ssk, centered double decreases, stitches knit/purled through the back loop, k-yo-k through the back loop, left and right lifted increases, some small bobbles, and a mock-cable Traveling Stitch. Instructions for the Traveling Stitch are included with the pattern, and can also be found at https://polychroma.com/knitting/stitches.html

The stitch count varies considerably through the chart. It will block with straight edges, though, because the added stitches go into the low-relief dimensional shaping of the design.
