Hi, is there anyone who could help me with this, the patter I am looking at, for both the back and front panels of a jumper, starts of the ‘armhole shaping’ section as follows:

"cast off 4 sts. beg. next 2 rows. Now beg. raglan shaping as follows -

1st row: k2 k2 tog. tbl Patt. to last 4 sts. K2 tog. k2

2nd row: k1. p2. Patt. to last 3 sts. p2. K1.

rep. these 2 rows until 58 sts. remain at end of a right side row. now dec. 1st at each end of every row as follows"

Most of this is fine, but I’m confused about the last part, “repeating until 58 stitches remain”… can anyone explain this?

thanks
