Tie backs are loops or bands of fabric that hold curtain or drapery panels back from the center of the window. You can make curtain tie backs with matching or coordinating fabric to custom window coverings. Most tie backs are 1 to 4 inches wide, but the lengths of the tie backs depend of the amount of curtain being pulled to the side. So it best to have the curtains sewn and installed before making the tie backs.
Measure the curtain to determine the amount of fabric needed for the tie back. Draw the panel to the side of the window, being careful not to expose the window molding. Wrap a measuring tape around the panel at the desired angle, making sure the tape aligns with the tie back hook (See Tips and Resources.)
Fold the fabric in half lengthwise so that right sides are together. Pin the raw edges together, but reserve a 3 inch gap opening in the center. You will need this gap to turn the fabric inside out once it is stitched. Machine stitch a ½ seam from one end to the opening. Use a backstitch, or a few stitches in reverse to prevent the thread from pulling out.
Hand stitch the opening closed with a slipstitch. (To do a slipstitch, thread a needle with a single thread strand that has a knot at the end. Insert the needle from the inside of the tie back so that it is under the seam allowance at one end of the opening. Bring the needle out in the pressed fold.
