Knitting with Creative Melange Aran Wonderball from Rico is fun and a little bit addictive. This cardigan and jumper from Rico use only two or three balls (depending on your chosen size). The cardigan features two front pockets and is worked primarily in stocking stitch. The jumper is worked sideways from cuff to cuff, which means less sewing to do afterwards! Available in five sizes, with finished measurements ranging from 96cm (37.75in) to 138cm (54.25in) for the jumper, and 111cm (43.75in) to 47cm (18.5in) for the cardigan.
