This calls for 5 strands of various yarns held together, so it would be difficult to enter them all here. Check pattern for details.

Very easy, very Vogue oversized coat knitted from multiple strands of bulky yarn held together (two strands each of yarns A and B and one of C). Reprised version of a design originally published in VK Fall/Winter 1968: see Chunky Coat.

From Vogue Knitting Fall 1999:
“Take fashion into the fast lane. Worked in the same stockinette and wonderfully textured garter-stitch border as the 1968 original … this cozy coat is ready to move.”
