This eight sided shape gives an interesting visual shape, but needs a friendly square to hold it together.
Jennie guides us through drawing your own Octagon shape, for use in patchwork with the help of a compass (or is a pair of ?) so you can then create the template whatever size you like. She also reminds you that this shape will not tessalte on its own (unlike the hexagon) so needs a friendly square to keep it company- and how big should that be?! well you need to watch to find out!
Jennie has the same neat trick of using a compass to draw up a hexagon – which you can watch by clicking here.
