One of the most important things any crocheter should learn is a variety of stitches that enables them to vary the textures of projects that they make, adopt the correct stitch for the form and function of the project they are making, as well as just having fun doing different things. The loops-in-loops stitch is an easy way to make a strongly textured, lacy project which nevertheless is strong and resilient. The beauty is that it uses chains that are then enclosed in a loop. Basically, you would be combining one of the simplest stitches (a chain) to make a structure of chains. This will be a useful and fun building block in your crochet toolkit. A link to the free pattern is at the end of the post.
