This pattern was done on the CinDwood 72 peg 3/8” gauge loom but the pattern is also written for the 80 peg 3/8” gauge loom.
It is a simple hat that mostly uses wraps and turns to complete, so I would say a experienced beginner could do this pattern.
It includes video, written, and picture instructions.
I also used exactly 1 skein for the smaller size but when making the larger you will need more than 1 skein of the Lions Brand Unique Yarn.
