The blouse is knitted top down in the round.
First, a hem is worked in broken rib pattern, then worked back and forth in stockinette with increases and edges in broken rib pattern.
Once all the increase rows for the yoke are completed, the pattern continues according to chart, first back and forth and later in the round.
Next, raglan increases are knitted, and the work is divided for the sleeves and body. Sts are cast on for the armholes, and while the sleeve stitches rest, the body is worked in stockinette in the round and finished with a broken rib stitch edge.
The sleeve is worked in the round in stockinette with decreases, and it is also finished with a broken rib stitch edge.
