Super easy cardigan pattern for boys and girls with a great Fair Isle look. Written in standard U.S. Crochet terms. There is only 1 pattern with sizes achieved by changing hook and yarn weight. Calls for 5 buttons with instructions included on how to make your own buttons with matching yarn. No fancy stitches (sc, hdc, hdc 2 tog, dc, dc 2 tog ch), and just 1 color per row and it’s SEAMLESS!!! This is a true whip up project.
