This T-Shirt yarn weighs approx. 650-850gms and contains approximately 100-140 metres. Originally used mainly for Crochet, it quickly developed a huge following by the Knitting community and not long after was being used to create magnificent Macrame masterpieces. It has been salvaged as left overs from the textile and fashion industry. Knots and imperfections are common in all T-shirt Yarn as it is a reclaimed product. We recommend using a size 10-15mm crochet hook, or size 10mm or above knitting needles. Please note that all T-shirt yarn is weighted in store as 800gms unless weighing more, this is due to postage restrictions.
