From pattern:
The unusual Coin Cable forms the lower hem and the back neck of this cabled sleeveless vest; the “coins” flow into the ribbed panels of elongated Firefly Cable which form the body. The cable twists are not only decorative; they also reinforce the point of the “V” neck and the bottoms of the armholes. Worked in the round to the armholes, this vest knits up quickly in a heavy worsted yarn—especially since finishing is minimal. Although the intended ease is 2 to 4”, the ribbed fabric skims the body contours, so the vest will not look baggy if you opt to knit a garment with 5 to 6” of ease. The refined details, handsome fit and coin trim earned the name “Florin,” from the gold coins minted in Florence, Italy in the Middle Ages.

Difficulty
Adventurous beginner to intermediate: skills required include working in the round, increases and decreases, reading charts, cable knitting, keeping accurate count of rows, short row shoulder shaping, and three-needle bind off. Skills NOT needed include picking up stitches for edgings and sewing seams! There are no seams to sew (shoulders are seamed using three-needle bind off) and all edgings are worked along with the body of the vest!
