2-color broken seed stitch sections: fabric too loose on 3.5mm, just right on 3.25mm. Getting neatest results for the straight garter-stitch edge by picking up yarn from behind at beginning of each row, and twisting the yarns at the beginning of row 2a - but not too tightly.

MC: nameless Shetland in dyed black (bought from a Danish designer many years ago)

CC1: Black Water Abbey 2-ply fingering in Ecru
CC2: Kate Davies Buachaille, Highland Koo (single strand)
CC3: Jo Sharp DK in eau-de-nil green (single strand)

Finished with 2 rows CC1, then Icelandic bindoff on RS. No bobbles.

After a light blocking, dimensions are 96” across the top (!), 26” down center back. Large and lovely. Total weight 280 grams. Used somewhat less than 125g main color (black) and 150g CC1 (natural).
