This knitting pattern is an original design, shown here in Paton’s Ballybrae, which is no longer available as far as I know - unfortunately. It was a heavy weight worsted with a tweedy finish.

The vest is knit in pieces and then seamed. There is a knit-on I-cord around the front & neck edge as well as around each armhole.
