Measure the side of the tapestry that is going to be topmost and add 1 inch.
Cut a strip of fabric that is 8 inches wide and as long as the measurement you found in Step 1.
Fold down both narrow ends of the strip of fabric twice, making creases that are ¼ inch deep both times, and sew them flat. This gives you a rectangle of fabric with two finished shorter ends.
Fold the strip of fabric in half along the length, and iron the fabric flat.
Sew along the raw edges of the fabric, creating a tube.
Spread the tapestry on the floor, the rear side facing up.
Line up the sewn edge of the tube with the topmost edge of the tapestry and secure it with pins.
Sew the edge of the tube to the topmost edge of the tapestry.
Remove the pins. The tapestry is now ready to be strung onto a rod and hung.
