This is a V-neck cardigan sweater knit bottom-up in one piece to armpits, with short sleeves knit in the round to armpits, then all are joined on one circular needle and yoke is knit in one piece decreasing to back of neck. Everything is charted. Waist and sleeve shaping is accomplished by changing needle sizes. Different yarns and gauges will change the sizing dramatically, so be sure to swatch with your chosen yarn to get the effect desired.
Addendum: Start body with size 7 ( largest)needle.
This is an advanced and challenging pattern with charts and complex lace patterning, but lots of fun to knit.
