0 Weight is the lightest weight of yarn. Lace weight produces an extremely fine gauge fabric. Lace weight yarns are often knit or crocheted on larger needles and hooks to create lacy, openwork patterns. Accordingly, gauge range is difficult to determine. Lace weight yarns are often used for delicate shawls and wraps.
