I picked random to try the yarn and check the color. the seller sent 10 different colors, all labeled with their numbers. some of them are quite nice. the material is some kind of mix of synthetic and natural fiber. burn test has both hard lump and black powder produced.
product looks like the picture. shipped and arrived quickly. seller sent me the color I wanted and it matches the picture. the yarn is quite thin. I put two strands together and 2.75mm or 3mm knitting needles work fine. feel soft and elastic. I did a burn test. it smelled but also melted to a hard ball. I thought the label reads all organic material, maybe I understood it wrong.
