Turning chains can be a real headache in crochet. First you need to understand their basic function: to get the hook up to the right height to start making a new row of stitches. Then you have to remember that turning chains are different lengths for different stitches (although some patterns use more or fewer chains). And you need to check whether the turning chain counts as the first stitch – with most stitches it does, except double crochet, but not always.
Then there’s the appearance of turning chains. They look very different to the crochet standard stitches they sit next to. And they can create a larger gap in the fabric than the gaps between the standard stitches. And the edges of the fabric can look a bit wavy rather than straight. Many people would probably never notice these little details, but if you spend enough time looking at crochet fabrics you start to wonder whether there’s a better way to make a turning chain.
