I had planned to put out tips and techniques posts in a logical order. This probably isn't going to happen as I'm not that organised and also because I'm better at writing on a subject that is in my head at that time.
There are vast numbers of colourwork sock designs around, such as Rachel's Alfrick pattern.
I always wondered how you would keep track everything if the floats were hidden in the centre of the tube. The answer of course is that you don't have to.
Quite simply, you work the sock inside out. It's easier to ensure that the floats don't pull too tight if you can see them, after all. For me, working a tube inside out hasn't ever been a problem as I picked up magic loop a bit wrong. In fact, if someone demanded that I knit the right way out, I'd really struggle.
There are a couple of ways to flip around your work. The simplest is to work the edging as you normally would and turn the work inside out when you came to the colourwork chart. Or you can do what I do and work magic loop with the cable between me and the tube from the start.
If you're eagle eyed, you'll have picked up that this isn't a sock, but a sleeve. That doesn't really matter since the idea is the same. What you will notice though is that there are places where I had to carry the yarn across the back of 5 stitches. With everything on show, I can ensure that the floats don't pull too tight, puckering the fabric.
I don't profess to being a colourwork expert and I'm sure there are many people out there with a wealth of expertise, so if you have any tips of your own, please do share.
If colourwork isn't your thing, but you do like cables, there's a KAL for the Sidney and Eugene patterns on the CoopKnits Ravelry group.
