Granny knows best!
Granny squares are fun and once you have the crochet basics they are quite simple to do. They are a great way of using up ends of yarn and can be joined together to form a variety of crafty projects, blankets, throws, scarves, cushions, bags etc. This is not a tutorial, just the pattern, you will need to get to grips with the basic starter crochet stitches first, but once you've got those down it's be granny squares galore!
It doesn't really matter how thick your yarn is (as long as you use an appropriate hook size for the yarn you've chosen) the squares will vary in size depending on yarn thickness and how loose or tight you crochet. For me granny squares are just a fun thing to make, don't worry about trying to make them perfect.. just have fun! Use as few or as many colours as you like, make them as big as you like (just keep adding more rounds). It really isn't as hard as it looks! I learnt to make mine using this pattern..
