I frankly don't see where it matters, all the definitions say "normally flush", but its still a matter of preference.I explain both methods in my tutorial and leave it up to the maker.I also explain both ways when I teach students.My personal preference is recessed and yes I have done raised inlays, though many hides do not lend themselves to being padded.I am reasonably sure that I have done more inlay's than most on this forum, because that's what I have chosen to specialize in for 20 years.I have also done some filigree work, which i consider quite a bit different.I have always strived to try new things and have inlayed all kinds of exotics, stones, wood,Ivory,carbon fiber, and different kinds of metal, while certainly not traditional, they were well accepted.I just don't see being close minded when it comes to artwork and I think it stifles creativity.Dave
