Untwine and straighten out the hanger.
Form one end of the hanger into a hook. Wrap the hook around the straight part of the hanger so it is in a circle formation.
Pull the pantyhose over the hanger, circle end first. Position the hanger so the circle end is in one legging, and the fabric is pulled around it fairly tight.
Form the bottom of the straight edge of the wire into another hook. Fasten that on the microphone stand. If the makeshift filter does not remain in place well, secure it with duct-tape.
