You could put a bunch of the sacred prayer cards on a chain and then chant the sacred prayer card Prayer over and over again as you work your way through the chain. Careful. You're getting awfully close to imitating a Methodist prayer rope, LOL.
John Wesley also used the prayer rope, a rope on which he tied knots for use in counting a short Psalm prayer or the Jesus Prayer of Orthodoxy. Modern Methodist prayer books still recommend the making and use of such prayer ropes!
