Question: how to make a yarn over at the beginning of a row?
Answer: Place your right hand needle through the first two stitches on your left hand needle, as if to knit two together (for a YO, K2tog). 2. Instead of knitting your stitches, simply wrap your yarn 'over' (up and around) by bringing it through the front and around your right hand needle. This is your 'yarn over.
