I have noticed that the perlon cord curls upward. How can I straighten it?

You may find that the perlon cord curls after it has been rolled up for an extended period of time. The weight of the object you want to hang is usually enough to straighten the wire again. If this does not achieve the desired effect, you may want to try hanging a weight on the wire over an 6 hour period of time. You can accelerate this process by first soaking the wires in warm (not boiling or hot) water for several hours.
