I think I'm having a "stoopid" moment...I can't seem to understand the following instructions from a mitten pattern. This is my first attempt at a mitten. My issue/question is with the highlighted text:
Round 1: *K1, p1. Repeat from * to end of the round.
Repeat Round 1 until piece measures 2" or desired length from the cast-on edge. Purl the last stitch of the round.
Round 1: Slip the last purled stitch from the previous round onto the working needle. This will be the first outside gusset stitch. K2, p1. The base of the gusset is formed.
Now, if I just purled the last stitch, isn't it already on the working needle?? Why would I need to slip it on to the working needle? BTW, this pattern is supposedly designed for magic loop (which I'm doing) and not for DPNs or 2 circs. I'd appreciate any and all help and explanations.
