You only need the "eye" portion of two peacock feathers. The overall length of the feathers should be between about 4 and 5 inches (13 cm). Apply a dot of hot glue to the back of each feather and press the feathers against a plain metal hair clip or barrette. The feathers should be slightly fanned away from each other. They should also be pointed up and out at a mild angle. Cut three circles of varying sizes out of scrap synthetic fabric.  Choose a blue, green, or black fabric so that it matches the feathers. Make sure that you do not choose a flammable fabric. The material you use should be relatively flame-resistant. The largest circle should be about 1.5 inches (4 cm). The middle should be about 1 inch (2.5 cm) and the smallest should be a little more than 0.5 inch (1.25 cm). The sizes and shapes of the circles do not need to be perfect, though. Use a lighter to slightly melt and curl the edges of each circle.  This is why it is vital that you use a non-flammable fabric. Hold the edges of the circle near the flame, but do not allow the fabric to touch the flame directly. The edges should curl even without being directly immersed in the fire. Stack the circles and sew them together in the center using clear thread.  The largest circle should be on the bottom and the smallest should be on top. Stack the circle slightly off-center from one another in order to create a flower shape. Hand stitch a few small, translucent beads in the center of the flower to create a center. Use the same clear thread. Apply a generous dot of hot glue on the back of the flower and place it onto the remaining visible portion of the hair clip. The flower should cover the stems of the feathers.

TL;DR in Indonesian:
Rekatkan dua bulu merak kecil sebagai klip rambut. Potong tiga lingkaran dari kain. Lelehkan tepi dari kain. Jahit lingkaran-lingkaran itu untuk membuat bunga. Jahit manik-manik di tengah bunga. Pasang bunga ke klip rambut.
