Take the thread and tie it tightly around the bangle. Make sure that the knot comes inside the bangle. Start wrapping the bangle with embroidery thread. Tie the thread tightly and neatly and do not overlap the thread. You need a lot of patience to finish this work.
After you have done with wrapping tie the thread tightly n the inside of the bangle. Cut off extra thread. You can apply some glue to the end of the thread. Now the bangle is ready to wear. Try it with different colours and different types of bangles.
