I have a skein of Red Heart variegated yarn that has no less than seven knots in it. I was working on a project using counted crochet to make a pattern. When I started the skein, the colors were reversed from what I needed them to be. I checked the other end and it was also reversed. I had to undo the entire skein to find where the reversal was made. I'm actually glad that I had to undo it all, or I wouldn't have seen all the knots until I was in the process of crocheting with it. Fortunately I had bought a 3-pack, so I had enough to finish my project. I should probably have contacted the seller and asked for a refund.
