Twin Trees II
Pattern is actually from Barbara Walker’s Third Treasury. This is a stitch pattern not a pattern.
From the Chapter Description: Most methods of charting cables have been notable for their incomprehensibility. Cable charts, as a rule, steadfastly refuse to look anything like the patterns they represent; also, they perplex the knitter with tangles of interlocking arrows and lines going in all sorts of directions. It’s not hard to understand why cable charting can be a problem when you consider that there are well over a hundred possible ways of working a cable crossing.
