Side seams

This type of seam is also invisible and is worked with the right sides facing. Place the two pieces together with straight edges touching and work back and forth from one piece to the other picking up the bar of yarn of the first row at the side of the edge stitch of one side, then draw the pieces together by picking up the bar of the second row on the opposite side. Continue inserting the needle from one piece to the other as shown in the diagram.
