Only started and I am already late with this series! You know me. I will start with some considerations on yarn, needles and gauge. The pinhole cast-on will be explained at the end of the post. Like for any other project, before you start, you need to choose your yarn and needles. Once you have done that, you need to know your gauge in order to decide the total number of stitches you will use for each round. Note that, except for the toe region, this pattern consists of a straight cylinder with no shaping, that is, no increases or decreases. The total number of stitches is the number that corresponds to the circumference of the foot. If you have already knitted socks with this yarn and needles, which is my case, you already know this number. If you have not and are feeling brave, I have got good news for you, because we are working toe-up socks , you do not need to knit a gauge swatch. You can just cast on straight away and work the toe increases until you are happy with the width....
