This uses the Soft Granny Ripple pattern (Pattern included) and a range of colours in the order of the spectrum to make the single bed blanket shown in the photograph. Helpful charts and photographs are included.

Information is given to enable the width and length of the blanket to be altered.

As pictured: it uses one ball of Stylecraft Specila DK 100% acrylic yarn in 15 spectrum colours plus two balls of Bluebell and 2 balls of Silver coloured yarn. 19 balls in total. Only about 10-15g of yarn will be left of each ball at the end.

It could be made in other yarns if similar colours were available.
