Take a 20cm long piece of thread. Attach it to the right side of Part 3. Thread all parts with the right side face down and wrong side face up, starting from Part 3, continue as follows: 4-5-4-3-2-1.

Make a tiny stitch and thread the parts in the reverse order. Do not pull the thread too much. Straighten the scales, fasten the thread.

Use the tail of the thread to make a loop. 

Paint the edge of the scales with white paint and DRY brush as shown on the picture.
