This pattern is part of “Stitching in the Stacks” from Cooperative Press.

Note: This will be corrected in the printed version of the book (and any subsequent digital editions), but the abbreviation sk2p in this pattern means slip 1 stitch, knit 2 sts together, then pass the slipped stitch over the k2tog. This abbreviation was accidentally omitted from the Abbreviations page. In the chart, the symbol that is listed in the key as sl1, k2tog, psso is the same as sk2p.
