With tapestry crochet, one yarn is single crocheted, while another is carried. Colors are switched while 2 loops of the unfinished single crochet stitch are still on the hook. The motif is visible on both sides of the fabric, with no floats on the back. For more about this hat, please look at my blog and for more about tapestry crochet, please look at my web page. Instructions and graphs are included for right-handed and left-handed crocheters.
