Weaving Stitch - To seam cast on+bind off edges Lay one piece garter stitch fabric above another. Notice that each row has linked upper+lower loops. Sew through upper loops on bottom piece+the lower loops on top piece, as shown below. You are creating sewn stitches over existing loops. The tension your sewing needs to be just right, neither too tight nor too loose. As you practice the stitch it becomes easier to judge tension+make an invisible seam.
