Once you've mastered the moebius cast-on the rest of this scarf is pretty straightforward. It's worked in seed stitch so that it's the same on both sides. I think a moebius works best when the twist reveals a consistent pattern on both sides.
It's been knit using Costa Brava Knitting's Double Knitting Pure Merino in Buttered Caramel with a contrasting trim knit in their Heather Mist using 4 mm circular needles with a 100 cm cord. It's taken about 75 to 80g (150 to 160 metres) of the main colour and about 15g or 25 to 30 metres of the contrasting colour. The finished scarf has a diameter of about 40 cm.
