If you’ve ever run into a big knot in your yarn while working on a project, this is a great way to join in your new strand of yarn. The Magic Knot joins two strands of yarn together with virtually no visible ends. It could even be used to join a new skein and avoid weaving in ends!
This technique is best used with a dense stitch pattern like garter stitch or seed stitch. A more open stitch or lace won’t hide the knot. It is also best used with a sturdy plied yarn. Single plies and delicate fibers aren’t strong enough to hold up to the strength test and will fall apart.
