Yarn set with various colors, perfect for knitting. Thank you for viewing. The height of all six skeins is just under 20cm. Please see the images for the weight. I was knitting with these as supplementary yarn for machine knitting. If you knit by hand, you can use two strands together to make it a bit thicker, so I think you'll be able to knit with them. These are items stored at home. I have a long-haired cat, so please refrain from purchasing if you are concerned. Thank you.
