15 colors of 100% cotton embroidery floss. Total of 40 feet. FREE SHIPPING. A note about embroidering with indigo: Minimal residual indigo colorant may temporarily color your fingers and hands while you embroider. 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.
