Start with two simple I-cords, add a connecting cast-on, and soon you are into a bit of lovely double-knitting.

From the I-cord straps to the heart-emblazoned crown, this sweet little hat is knitted entirely in one piece. It is, of course, perfectly reversible, and will keep a little head very warm. See my instructional DVD, Double Knitting Delight, to help you learn the wonder of double-layered knitting.

Susan and I have filmed two supporting Youtube clips to help you get your bonnet started:
I-cord Edged Double-knitting and
Tubular Cast-On and Incorporating I-Cords

A kit for this project is also available.
