New to knitting jumpers and I’m struggling to understand the instructions for increasing on the sleeves. It is written as follows:
With 4.5mm needles cast on 34 sts. Work 4 rows in k2 p2 rib. Change to 5mm needles.
Next row: k3, m1, k to last 3 sts, m1, k3.
Begin with a p. Row, cont in st st and work 17 rows.
Inc as set on every foll 8th row until there are 56 sts.
Work 21 rows straight after last Inc.
The starred/italics section is the part I don’t understand. Where and how many sts do I increase on those rows? Thank you for any help!
