Say you're finish creating the bangle and now ready to fill the leaves with wires. Cut 90cm (35 inches) x 28ga wire. Wrap or coil the wire at least 2 times onto the base of the leaf frame shown in arrow.
Then bring the wire up, under and around the upper leaf frame and wrap 2 times.
After wrapping 2 times bring the wire down, under and around the lower leaf frame and wrap again 2 times.
Continue to bring the wire down, under and around the lower leaf frame and wrap again 2 times. Repeat the same wrapping technique until you fill the leaf frame with wires. When finished make a final wrap securely and cut off excess wire. Do the same for the other leaf.
