This colourful book puts a fresh twist on a classic granny square, offering inventive flat and 3D motif designs. Variations include a vibrant '60s  Retro Flower, a heart with a scalloped edge and a Pastel Grid with an ombré effect. While some designs play with colour and pattern, others feature stitches such as loops or bobbles, and there are suggestions for mixing and matching squares throughout.
