naturally dyed indigo linen paper "Very unique paper yarn made from linen. For an additonal strength, a few strands of almost invisible raw silk is wrapped around it. This is the truely natural indigo dyed yarn. Due to the nature of the indigo dye (indigo basically only lies on the surface of the yarn.), the color tends to bleed for a while, but it will settle down and settle down to an even better blue by aging. Works as a warp yarn for weavers.!"
