In the pattern for the body, what does it mean by "With right side of work facing K across the 20 sts on knitting needle, then across the 20 ss on the spare needle - 40 sts"?
I don't have the pattern to hand, but going from memory, each leg is 20 stitches and are knitted separately, then knitted together. So you knit the 20 stitches of the first leg and then put the 2nd leg onto the needle (from the scrap yarn/spare needle) and knit across onto the next leg. You then end up with 40 stitches on the needle, ready to knit the rst of the body.
Hope this helps!
