This post shows how to join two ends of yarn using the Russian Join. This is a great method to join yarn when crocheting or knitting. Unless you are knitting a pair of mittens, a hat, washcloths, or something similar, you will most likely need to join balls or skeins of yarn. The Russian Join eliminates knots in your work and the need to weave in the ends. https://nourishandnestle.com/russian-join-joining-yarn-for-knitting/
