Stretchy (elastic) Stitch

"The stretchy elastic stitch is a popular choice among knitters for several reasons. The primary advantage of a stretchy elastic stitch is its ability to stretch and bounce back to its original shape. This characteristic makes it ideal for items that need to accommodate movement, such as socks, hats, and garments. The elasticity ensures a snug and comfortable fit. When knitting items like hats or socks, it's not always easy to predict the exact size needed. A stretchy elastic stitch helps in this regard as it can adjust to a range of sizes, making the finished piece more versatile."
