The wonderful technique of double knitting creates a two-layer fabric with knit stitches on both sides. The finished fabric is completely reversible, which makes it perfect for colorwork, contrasting fibers, or simply a double knit-faced fabric that is super warm! A buff is a versatile accessory that can be worn as a headband, cowl, or ear-warmer. This pattern comes in two sizes (s/m, m/l) The s/m is good for an adult woman’s head and the m/l for an adult male. The yarn will stretch over time so opt for the smaller size if you think you are between sizes.
