To make a tassel, cut a 1 1/2-by-3-inch strip of paper in the same color. Make parallel snips along the length of one side, about 1 inch deep. Cut a 10-inch length of cord in a matching color and fold in half. Tape the cut ends of the cord to one end of the strip and roll paper tightly around the cord; secure with tape. Use a pin or needle to poke a hole at the circle in the top center of the envelope. Thread the cord's folded end through hole by 1 inch; secure the inside envelope with tape.
