We did this at the book launch on the 21st September so I thought I'd share it with you all. Take one hula hoop, 2 100g balls of chunky yarn (Patons Jamboree in our case) and a bevy of willing minions. Start by tying the yarn in a single knot around the hula hoop. Begin casting by passing the yarn through the hula hoop from back to front and then back through the loop created. This is a blanket stitch. Supervise your minions doing this first step as you eat some of the delicious cake they bought you to celebrate the launch of your book. Invite interested people to peruse your new Dorset button jewellery kits, available from the website soon, as your minions do their thing. Get your minions to take turns so they don't get tired (Shirley takes her turn) Once the casting has been completed, lay the spokes your self by wrapping the yarn around the hula hoop like the spokes of a bike. Make sure each spoke lies across the centre at the front....
