The easy-to-follow instructions allow you to make an afghan or wall-hanging in any yarn of your choice, to any size. It may look complicated but, if you can knit garter stitch, you can make this.
The design is based on the curves that are formed if four dogs set off to chase each other from the corners of a field. The path created by each dog is an equi-angular spiral.
The design changes dramatically depending on where you place the colours. All the examples in the photos are variations of the basic design. The pattern includes colouring-in sheets so you can plan your own afghan.
