This loom knit hat is worked with 2 yarns: an inner yarn which creates a sort of lining and an outer yarn which is mainly visible as lines or ribs running up the outside of the hat.

This hat, in three sizes, is worked from the bottom up, in the round, with no seaming. The Puff Stitch pattern is fast and easy to knit, and using self-striping yarn highlights the pattern and eliminates weaving in extra ends.
