Lace trellis, right bias

From Barbara Walker's A Treasury of Knitting Patterns, page 190. (I'd reverse-engineered this, and realized that it had to be in at least one basic stitch dictionary. It was, but I'm not seeing a map for it, so here it is.)

Shown with a cast-on count of 6 stitches.   Getting chart...

  • Row 1 (RS): K1, *yo, k2tog, repeat from * to last st, k1.
  • Row 2: Purl.
