Knitting Help - Correcting Gaps in Socks

Cuff-down or toe-up, there is always a chance that you'll get a hole in your socks right where the heel meets the rest of the sock. Here's how to keep that from happening. Information on things you'll see in this video: The yarn I'm using in my socks is Knit Picks Hawthorne Fingering, in color Irvington. One hank of this yarn = one pair of adult socks. The sock pattern I'm using is a basic toe-up pattern from Knitty: http://knitty.com/ISSUEsummer06/PATTuniversalsock.html The needles I'm using are Addis, size US 1 (2.5mm), 40" circulars. The sweater I'm wearing is a free pattern + video tutorial, which can be found here: http://verypink.com/2014/10/22/cropped-raglan-cardi-tutorial/ The nail polish I'm wearing is by Julep, color "Malala". http://refer.julep.com/s/stacip
