This yarn is sold in more than one put-up; yardage should be adjusted at the stash level.
Gauge of 21 stitches/4 inches = DK weight by Ravelry’s weight standards. 4.0 mm needles.
N.B. (GuardedOptimist) I have a different generation of this yarn. Label indicates that there are 24 stitches per 10 cm (4”) and calls for 3.75 mm needles. My generation would be Fine (2) weight (sport or baby).
