From the Shelridge Farms website: This colourful vest uses a technique developed by Vivian Hoxbro called shadow knitting. Simple knit and purl stitches combine to create the optical illusion of chevron-striped shadows passing across the surface of the knitting. The chevrons appear and disappear as the vest is viewed from different angles --- now you see them, now you don’t! Knit in our Soft Touch 4-Ply DKW 100% Wool in 5 colours.

Kit come in either a Pink/Blue colourway or a Green/Blue colourway. Price listed is for the kit.
