Joining a Round - Hook Placement - Crochet Tip 27
If you look closely at a chain, there are three loop strands that make up the chain. There are 2 loops at the top and 1 loop at the bottom. There are also 2 loops at the top of each stitch. Place your hook below the 2 strands of the joining stitch or chain, then pull your yarn through to join. Your round will have a more secure join by using this method. It will reduce the visibility of seams when making hats and caps.
