Knitting Help - Norwegian Purling

Norwegian purling is a way to keep the working yarn in back while you're purling Continental (holding the working yarn in your left hand). The yarn I use for demonstration is Knit Picks Wool of the Andes Bulky. The needles I'm using are Knitter's Pride Bamboo Double Pointed Needles. (No real need to use DPNs for this technique, I'm just using them here because they're short and they work well on camera.) My nail polish is by Julep, color "Channon". http://refer.julep.com/s/stacip
