Knitters love to make hats - and "One + One: Hats", the second book in Iris Schreier's exciting new series, gives them a stunning array of fashionable, functional and beautiful projects. Best of all, each one uses only two skeins of yarn! The hats come in a broad range of colours and textures, and Schreier explores a variety of knitting techniques, from knit and purl to lace; stranded colourwork and slip stitch; and double knit.
