What you need:
-feathers (pull them out of your pillow!)
Now, attach a piece of twine to the bigger circle and wrap it all around the iron wire, until half the circle is covered. I know this sounds like a dull thing to do, but it only takes a few minutes! I found it easier to do with a needle.
Attach the smaller circle inside the big one with twine, then continue wrapping the large circle and attach the small circle on the opposite side.
Also attach a bundle of twine at the top to hang it from later on. You can rope braid it if you like.
