'Bone Fragment' cabinet pull

I am designing and fabricating drawer pulls and cabinet pulls for a clients kitchen remodel. The client admires my work and knows much of my source of inspiration comes from the natural world. They have toured my house and seen my extensive collection of natural objects,stones,bones,shells,seed pods and skulls. They want to see these source works translated into hardware for their kitchen cabinets and drawers,AND they are fine with each one being different i.e. no multiples. I like that because I find reproduction on nearly every level to be tedious and diffuses the vitality of the original. The down side is that this it is much more work than creativity. But hey, what am I here for if not that?
Welded stainless steel.
The bolts must be exactly 3 inches apart to fit into the existing holes in the cabinets. I've made a jig that holds the bolts in the proper orientation and distance for welding.
