This spectacular afghan is much easier than it looks. It is worked in one piece, entirely in garter stitch, using one colour at a time and with a maximum of around one hundred stitches on the needles. There is a tiny amount of stitching to be done (and some darning of ends).
The version in the pictures was worked in DK yarns but you can use any yarn of your choice to create an afghan the size you want. You could even make it in a very small size, as a pillow. The pattern includes several variations of the design, using 2, 4 or 8 colours and different types of swirls and zig-zags.
This was our first afghan design not based entirely on mathematical principles. It relies on the pliant nature of the knitting to allow some distortion which creates the zig-zag swirl.
