Garter stitch is the simplest knitting fabric, made by knitting every row. It creates a squishy, reversible fabric of horizontal ridges that lies flat without curling — which makes it ideal for beginners, scarves, and garment borders.
Because it doesn't curl and looks the same on both sides, garter stitch is the go-to for a first knitting project. It's stretchier and thicker than stockinette, so it also makes cozy blankets and warm edgings.
