How to sew 2 pieces of fabric together by hand?

To sew two pieces of fabric together by hand, start by aligning the edges of the fabric and threading a needle with a suitable thread. Use a basic stitch like a running stitch or backstitch to sew along the edges, making sure to secure the beginning and end of the seam with knots. Repeat the stitch along the entire length of the fabric, keeping the stitches even and tight for a strong seam.
