A little trim never hurt anybody! The Trimmed Knot is your favorite Classic Knot headband with the added pom-pom or lace trim detail for the perfect finishing touch. This headband is one size fits most and the size cannot be adjusted. The headband is sewn at a 6" diameter (12" circumference), keep in mind that measurement is before it stretches. We feel this is the perfect size for our soft nylon to fit a newborn and stretch comfortably as she grows through childhood. The bow measures approximately 4.5" across. The trim is securely sewn to the edge of the bow. This style is sewn in two pieces and can be taken apart for hand washing or to mix-and-match. The Trimmed Classic Knot material is soft nylon, produced to our specifications, in the USA . The pom-pom trim is polyester and the lace is poly/cotton, both sourced in the US. Each headband is hand sewn and tied by women in our local community. Due to the nature of small-batch production color and sizing can vary slightly.
