Move them to where they are sitting with the flats of their feet together, but the rest of their pose is as if they were sitting cross-legged. You want approximately 8-14” of distance (depending on their size and flexibility) between their groin and their heels. If the person you are tying can not maintain this position for long, you can have them put one leg in this position (I begin by tying the left leg in this example), and their other leg is kept out straight until we are ready for it.
