Measure your waistline, using a measuring tape, to determine the size of your sash. Keep the sash approximately a foot and a half longer than needed to adjust the size and so it can be tied around your waist or hips. Make the sash approximately 4-to-8-inches wide.
Mark the required size on the silk and cut out this measured rectangular piece. Fold over the edges of the sash and use a sewing machine to make a finishing seam on all four sides.
Cut out 14 5-inch squares of silk from the remaining dupioni material. These will be used to make seven silk flowers to decorate your sash.
Fold one square in an under-over accordion pattern to make a rectangle that is half an inch wide. Hold the folded silk square in the middle by pinching it between two fingers. Sew the square in the middle, using a needle and thread, to hold it securely. Let the ends of the silk square fan out in a flower shape.
Repeat the folding and sewing with each of the other silk squares. You should now have 14 ruffled flower shapes. Assemble a flower by placing two ruffled squares on top of each other. Place a bead in the center of the top flower and hand-stitch them together using a needle and thread.
Lay out your sash on a table or other flat surface. Arrange the seven flowers on top of it in the pattern you wish. Hand-stitch the flowers to the sash using a needle and thread. Tie the sash around your waist over a dress or blouse to wear it. Or loop it loosely around your neck.
