A great sock can be made or broken within the first cast on. As a knitter we have many cast ons to choose from long tail cast on, knitted cast on, crochet provisional cast on, e-cast on, German twisted to name a few, for socks you don’t have to look to far into your knitting bag of tricks to find an oldie but a goodie, the long tail cast on.
For many this was the first cast on you learned. For me it was my second as I was taught the e-cast on first. The great attribute of the long tail cast on that lends itself so nicely to socks is the ability to control the tension of the stitches being cast on. When you place the stitch cast on to the working needle, gently secure it without over pulling and you will have the perfect sock cast on every time.
