Hello, thanks for your message! I'm very sorry that you found a knot in your yarn.
The mills we work with really try to minimise this happening, but the industry standard allows for a tolerance of up to 3 knots per ball as knots are a direct result of new threads being joined together during spinning. Here is a
link that has more information:
However, if you find more than this in one ball, or if you find joins in more than one ball in this shade in your purchase, please get back to me at info@lovecrafts.com with photos of the yarn and I will investigate the issue for you.Best wishes, Elizabeth and the LoveCrafts Team
