This silk thread, sold in 100 yard hanks, is primarily used for embroideries but can be used to weave tiny tapestries, braid into cord, etc. If embroidering, you can take apart the 4 plies for very fine line work or filling very small areas- each ply is much finer than a single ply of DMC cotton floss.
This batch has been dyed a purple-gray color, just a bit cooler in tone than the taupe wool. We dyed it with madder root and iron for the mordant. Madder root (Rubia tinctorum) has been used for millennia as a dyestuff. With various pH levels and mordants, it can produce orange and purple from the first bath and pink, orange, taupe, and grayish purple with the second bath. It usually has some of the best lightfastness and washfastness of all the natural dyes, especially with an iron mordant.
