In the double foot lock, cross the fabric behind the back elbows are between the fabrics, reach behind the head with one hand in front and the other around behind, pull fabric apart making a cross in the middle of the back. Push the cross over the hips to the knees, keeping the toes pointed outward. It is important to keep the toes pointed out so if fabric slips off the knees, it will be caught at the ankles. It is important to have a spotter for this trick.
To Come Out: Sit up.
