Under the "Gusset" section, it says:
Continuing to work on the same needle, pick up and knit 8 stitches along the side of the heel"
I can pick up 8 stitches, but how do I then knit those stitches? I would have to purl them, and it would get me to the wrong end of the needle for continuing onto the other two needles. Does it just mean to pick up those stitches, then go onto the other two needles? I just don't see how to knit them after I've picked them up.
