Hi Michael,

Thanks for your follow up to my questions...
In regards to arraying prongs, the prongs always follow stone placement and never the other way around.
For this type of stone setting, most of the time we want side-by side stones to share a prong on each
side so you have the stones laid out as close as possible to each other along the path curve on a surface
with just enough room for prongs to hold the stones in securely without too much metal showing.
So the prongs need to be just large enough, but not so large that they would obscure the stone
at all.
