The Loop Stitch is a two-row repeat crochet pattern constructed with alternate rows of single crochet stitches and loop stitches designed to create a fluffy textured pattern on one side and a flat, dense pattern on the other side. It works great for rugs, baby blankets, scarves and other garments.

Don’t be intimidated by the look of the loop stitch, it’s just a modified single crochet stitch that has a loop created on the wrong side. Once you get used to the steps of making a loop stitch, the process will become automated and you won’t have to count stitches or rows.
