NOTE: Broomstick crochet only uses one stitch that is worked with a crochet hook and a giant knitting needle, broomstick handle or broomstick needle that can be purchased or you can make your own. A dowel can also be purchased and cut to the length you wish and then one end sanded into a dull point. The broomstick will be held in the left hand (for right-handers) and the right hand (for left-handers). The size of the hook and broomstick, together with the number of loops being used, will determine the size of the stitch pattern.
