After 3 swatches, I am now ready to cast on for Stornoway. Here are the gauge results (from top to bottom):
3 mm needles = 13.5 st & 17.5 rows in 5 cmSince that 3rd result is precisely the required gauge, we're officially good to go. I'm happy too, because the 2.5 mm needles felt the most comfortable with the yarn.
2.75 mm needles = 14.5 st & 18 rows in 5 cm
2.5 mm needles = 15 st & 18 rows in 5 cm.
Eriskay will probably need at least one needle size smaller, because of its smaller row gauge (21 rows in 5 cm) — but that's a problem to be solved another day.
It's been a while since I last made a sweater in-the-round. This is going to be *FUN*...
