A note about knitting with indigo: Minimal residual indigo colorant may temporarily color your fingers and hands while you knit. This can easily be washed off with soap and water. This is a natural characteristic of knitting with indigo, and should not be considered a flaw or defect. We hope you enjoy knitting with this centuries old technique.
