This is a Debbie Bliss design from her Book "number three". It was originally in DK cotton but I tweaked the gauge and made it in Rowan Magpie Aran in Teal. I knitted it in 2002/3.
It's a great man's sweater but Mike has two complaints. It's REALLY warm, resulting in him occasionally getting overheated and having to tear it off, shouting "I'M ROASTING!!". And because the front and back both have a plaited cable, he can't work out if he has it on the right way round. Must sew in a label.
