My apologies to Kate Davies: I disregarded the instructions to backstitch the side seams together, opting instead to crochet them together. My logic was that the crochet seam would be just as firm as the backstitch, with the bonus of me having my sanity after its completion. And it worked!
I am now happily on to the sleeve edgings, which cinch in the ends of the sleeves, giving them a dainty little puff. Not very well visible in the image above, but I swear, it’s there!
After stepping back from knitting to make the neverending Modern Vintage Potholder, returning to simple, unadorned ribbing is glorious.
