Truffle is a vest that is a fun and relatively quick knit. It is made up of 4 pieces: the back, worked in stockinette stitch and 3 panels worked in a lace pattern. I-cords tie in the front to close.
The lace pattern is fairly simple, so a lot of lace experience is not necessary.
I would suggest using a soft yarn that will drape.
The pattern includes a schematic with detailed construction instructions.
