This knitting pattern was inspired by my Tunisian Diamond Jacket, for people who don't crochet but liked the pattern. It is worked mainly in garter stitch, one square at a time. The pattern has written instructions and charts. The options are endless, I have pictured a striped cardigan made with two shades of plain dyed yarn and a random/variegated version made with random/variegated yarn and plain. It is a good pattern for using all your left-over yarn up. Why not try a different colour for each square?
