We make three lengths of 1-1/2 cotton straps: six, eight and ten feet. A size label on each strap makes it easy for teachers and students to know at a glance which strap to use. The longer lengths are good for taller students and for bound angle pose. Our 10' strap can be joined into a circle to form a backless chair that gives tremendous lumbar support when sitting on the ground. Great for camping and meditation.
