This pattern is one of 3 patterns written for my 30th birthday celebration. Coincidentally, this pattern also uses approximately 30 yards of super bulky yarn. My sample is knit with Malabrigo Rasta, which yields about 5 WPI (some super bulky yarns may be too thin to achieve gauge, so please check gauge before starting). The 30 headband is written for adult sizes, but can easily be adjusted for other head circumferences. This knit is very quick and can be completed within a few hours of continuous knitting. A great option for gifts and craft markets.
