I love this motif. It's easy to work and gives a delicate touch to an otherwise boring stocking stitch scarf,
This scarf was worked in Posh Catherine (heavy laceweight) on 3mm needles.
Posh Dee describes Catherine as smooshy. I remarked that it knits to almost the same gauge as some sock weigh Posh bases and she explained it was all to do with the smooshiness (she assured me this is a technical term ;) ) of the yarn.
