Adding new yarn to your crochet project is an important skill to master. It allows you to create projects with different colors or textures, and to avoid running out of yarn in the middle of a row. There are several different ways to add yarn, depending on the type of project you are working on and the look you want to achieve.
One of the most common ways to add yarn is to simply tie the new yarn to the end of the old yarn and then continue crocheting. This method is quick and easy, but it can create a visible knot in your work. To avoid this, you can use a yarn needle to weave the new yarn into the last few stitches of the old yarn. This will create a more seamless transition between the two yarns.
