This pattern is very similar to the Shawl Collar Vest with chevron patterning available from Unicorn Books and Crafts.

Pattern available from Textiles A Mano (www.textilesamano.com) either at their shop in Eugene, OR or when they are vending at a show. At this time the designer is not sending it out individually. Check back in the future as it may become available through Ravelry.
