You will also need a stitch marker, and yarn needle. Please check your gauge! The range of hooks that might be used for this pattern could be anywhere from a 4.5mm - 5.5mm depending on if you are very tight crocheter. I am very loose and use a 4.5mm
This pattern works well using a yarn with a variegation or color change such as Noro Silk Garden, Kureyon, Mini Mochi Plus, or Crystal Palace Taos on the top section.

Use a solid color yarn that picks up one of the colors in the top part of the hat for the lower section.

This hat is lovely just plain or easily spruced up with circles or flowers and single crochet stitching on top. The pattern includes directions for the circles.
