Go through your stash and work out what you want to use up, then find a matching hook. I’m trying to clear some 8ply acrylic!

For this blanket you will need to know only basic crochet stitches - chain and half double crochet - worked in the back loop (half treble if you prefer UK terms) But you will also need to know how to decrease (crochet two stitches together) and increase (crochet two stitches in one)
