This is a rectangular stocking stitch wrap worked in a graduated stripe pattern, using twelve colours of Kidsilk Haze. The borders are worked in moss stitch.
Yarn requirements are one ball of each of twelve colours, plus an additional ball for the border colour - so 13 balls in all.
The pattern is written out giving the colour changes row by row for the first half of the wrap, for the second half the stripes are worked in reverse order.
This pattern is available for free on the Rowan website to members of Rowan Online.
