struggling with pattern instructions - Diana pullover by Adriafil
I am struggling to understand the increase, decrease and bind off instructions for the body after completing the pattern stitch from the grid.
Instructions: Back: Cast on 101-101-121 sts and work 86 rows in Pattern st. Evenly decrease on the last wrong side row sts to obtain 82-90-98 sts. Continue working in Garter st. At both edges increase 4x1 st, every 14 rows. When work measures 46 cm for armholes bind off 1x3, 1x2 and 1x1 st, at both edges every 4 rows.
When work measures 63-64-65 cm for neckline shaping bind off the center 40-44-48 sts and work each half separately. At neck edge continue binding off 3x4 sts, every 2 rows. When work measures 65-66-67 cm bind off shoulder sts.
Front: Work same as back until work measures 53-5455 cm. For neckline bind off the center 22-26-30 sts and work each half separately. At neck edge continue binding off 1x3, 2x2 and 14x1 st, every 2 rows. At the same time, for armholes decrease same as back. Bind off the shoulder sts at the same length as back.
Sleeves: Cast on 61 sts and work chart once; on the last wrong side row evenly decrease sts to obtain 52 sts. Continue working in Stocking st and for sleeve width increase 8-10-12x1 st at both edges, every 13-119 rows. When work measures 48 cm for sleeve cap bind off at both edges 1x3, 1x2, 9x1, 1x2 and 1x3 sts, every 2 rows. Bind off the rem sts.
Any help would be gratefully received.
