Long woven cloths are used around the world in a variety of ways to support labor. Tie a knot in one end and close it in a door to hang from. With mom on all-fours, the partner can drape it across her bum and use it to gently juggle her lower half, removing tension. Or, in this same position, drape it under her belly and the partner can gently lift to take the weight. Or, tie it tightly around her hips for counter pressure on the pelvis.
The options are endless, get creative!
