The “EZ” in this pattern title does not refer to its difficulty rating. Instead, it is the initials of Elizabeth Zimmermann. and as such is a modification of her “Heart Hat” pattern which can be purchased online through Schoolhouse Press. It incorporates mosaic hearts into the body of the hat which are built on the Dotty Heart Chart from Dotty Knitting “A Workshop by Suzann Thompson” and can be purchased through Ravelry. If you are interested in mosaic knitting and would like to learn more, I highly recommend you purchase this workbook, whether you are a beginner or not. It is a great way to learn how to knit mosaic in both stockinette and garter stitch patterns, make nice borders and graph your own designs.
