Aerial Silks:Aerial Dance Footlock
From a climb, separate the silks and hold them about 3 feet apart from one another. It helps to hold them next to your shoulders, with your arms bent.
Take your feet off the silks, and push them around the outside of, through the silks, and back behind you as far as you can.
Circle them around the silks wide and come back through the middle of the silks, then behind you once more.
This can be done with both feet at once, or alternating twists in an "eggbeater": left leg twist one, right leg twist one, left leg twist two, right leg twist two. Try both and see what works for you.
Bring your feet together below you with straight legs. This position will support you. If you forget to bring your feet together, it's much harder to maintain this position.
Pull up a bit and step your feet back into the slack 'stirrups' to create a footlock. You can do this one at a time to get used to it.
You can do this one at a time if you wish, which eliminates the need for using your arms so much in a pullup. However, it's somewhat easier to get even footlocks if you do them both at once, and it just looks showier.
Note that these footlocks wrap opposite of the traditional figure-8 footlocks. The silk poles will end up outside of your feet rather than on the inside.
To get out, just pull yourself up a bit and push the poles off your feet towards the back. This is opposite the direction of a figure-8 lock, in which you exit by pushing the poles off the front.
