Gaufrette gauge
23 sts and 38 rows in 4” / 10 cm on (Larger) needles in stockinette after blocking.
28 stitches and 40 rows in 4” / 10 cm in 2x2 ribbing on (Smaller) needles, after blocking.
This is a tight row gauge, which is why alternate instructions are provided for 28 rows and 33 rows. Swatch to meet stitch gauge, then measure the row gauge of your blocked swatch and follow the row gauge instructions that match it most closely.
The alternate yoke instructions require less yarn, see yardage for details.
