Using 3.5 mm needles, my swatch gauge is 28 stsx40 rows.
The cotton/linen is used in one ply and the merino/silk in three plies.

I cast on 160 sts for the yoke with 2.75 mm needles but I wish a less wide neck, I will work some short rows.
after the ribbing sts and before starting the neck as the pattern says, I have worked three pairs of short rows at 37, 30 and 24 sts from the beginning . Seems OK for my head

The Sweater is finished and the yarn blend is perfect for Spring time. My daugther love it
