Artist Statement: Double Vision is a stunning afghan. It appears to have 55 different shades though it only uses 10 ordinary, easily available colours. The afghan you see in the photos was made in DK (Double Knitting) yarns. In theory, you can use any yarn of your choice but,in reality, yarns heavier than DK would make the afghan uncomfortably heavy. You could make a floor rug instead, if you wish to use heavier yarns.
