Things you need to know: (Read this section before starting pattern)
~ When you see (parentheses), this means that you need to complete all stitches in the (parentheses)

~ You will be working from the brim of the hat to the top.
~ You will need to know how to do the raspberry stitch, the make one increase, and knit cables. I will provide links down below for all of these techniques.
