1 kilo cones. 100% cotton. Light yellow. An excellent quality machine knitting yarn which can also be used for fine crochet / lace work or tassel making. I used this type of yarn to make my Knitted Chandelier pendant light-shades which sold in Harvey Nichols, Liberty, The John Lewis Partnership and stores around the world. This should give you an idea of the kind of yarn quality as these are very discerning stores. It can be used on a single or double bed knitting machine and gives a very nice soft fabric once knitted up. Some swatches are shown to give you an idea of how it knits up. Great for garments for both adults and children, beanie hats, cot blankets, booties and throws. As a really rough guide, 1 kilo should easily be enough for an adult jumper with some spare (obviously depending on the design and size).
