One of my husband's finer qualities — among many fine qualities — is that he likes wearing hand-knits. This one is the British Schoolboy Vest from Cheryl Oberle's "Folk Vests." It's a handsome, traditional vest that I knit in a non-traditional color — purple.
The specifics: Wool Pak 8-ply wool in color Plum (it really is the color of a ripe Italian plum) knit on US4 and US2 needles.
I've made several of the vests in "Folk Vests." It's a great book.
