I’ve filmed this as a video tutorial over on YouTube rather than write up a pattern [pop over to watch HERE]. I cover the magic knot, making up the granny stripes and then lining it too. All in eighteen minutes! I also recommend you visit my zip video too [it’s HERE]. If you’ve never put a zip in your crochet before it might well prove useful.
You can use any yarn, along with your favourite corresponding hook size but there pretty much are no rules to this. Ok, there’s one rule: you need multiples of 3 plus 1 for the starting chain. Even if you’re a stitch or two out then I’m sure you can fudge it. Crochet is very forgiving.
