This is an ultra-fine, nylon-like thread. I don't know the exact material, but it's not cotton. I've used it to make tassels and to knit with other yarns, but I have too much left over, so I'm selling it. It seems to have almost no stretch. I haven't used it myself, but it might be usable as sewing thread. There's a large amount, so please use it without worrying about making mistakes. Please use your ideas to try various things. There's a lot of length, so I used it without worrying about mistakes. Weight: Approximately 1030g (including the core) #ConeThread #Yarn #Knit #HandKnitting #MixedYarn #Knitting
