I am working on a pattern for a teddy bear and I am stuck on a line of the pattern. Working on the body of the teddy and have gotten partway through the face shaping section.
41 sts on the needle
14th row states: P20, cast/bind off 1 st, p20.
15th row states: On 20 sts, k18, k2tog. 19 sts. (this is the row I don't understand)
16th row states: P2tog, p17. 18 sts.
On row 15, what does "on 20 sts, k18" mean? How do I get from 40 to 19 sts on that row?
I have only been knitting for a couple of years and have not seen this before. Thanks.
