Make a 45 degree bend about 1" from the end of the short end of u shape.
Hold the u shaped looped end with pliers and use the wire you just bent to wrap around the loop.
Using dowel or knitting needle, bend the loop into a hook.
Using pliers, turn up the end of the hook. Use pliers to shape hook.
From end opposite of hook, thread on desired beads. Be sure to choose beads that have an ample opening. I like to use small beads on each end of my beads. This helps to keep all the beads from sliding around. Once you have all your beads placed as you like, use dowel, knitting needle, sharpie etc to make a loop or double loop for the spring.
