Still no drill bits.....

It would seem the particular drill bits I am seeking can't be found in your bog standard DIY Store!!  Looks as if I will be gracing Ebay this evening!
Well I was struck by a bolt of inspiration this morning!!!  I have created a Valentines, Tigers Eye Heart Copper Bangle...........................

Had I had my drill bits I would have added the Tigers Eye differently, no matter I think it turned out ok.  Haven't worked with Copper like this before.  After being hammered it certainly is tough to curl the ends!!
