These shorts are made from Coton Fifty yarn (50% cotton and 50% acrylic). Vertical crochet chains give this stripy patterned knit its chequered effect. Just add a length of flat elastic on the back of the waistband to make sure the shorts stay up! This pattern is aimed at knitters who have also mastered the basics of crochet and is knitted in 1x1 rib and stocking stitch on 2.5 mm and 3 mm needles. The vertical lines forming the squares are added using a 2.5 mm crochet hook. Size 6 months requires 3 balls of yarn. The shorts are machine-washable and can be tumble-dried.
