hmmm, that's weird. i posted a 'thanks' and a few answers to questions earlier today and now it's gone. if it doesn't reappear by tomorrow i'll try again...
well i guess my first reply has been lost in cyberspace- better luck with this one...
first, thanks to all for your kind comments!
Sam- i use pure platinum from Hoover & Strong, as opposed to 90/10 or 95/5 jeweler's alloys. it works about like 23.5kt(?) gold, but is not quite as forgiving. i'm more careful about matching the size of wire or sheet to the cavity as platinum isn't virtually infinitely ductile like 24kt.
Mark- the shadows are just lots of medium fine parallel lines cut with a 90 sq. sharpened on a 600 grit wheel- no polish.
using shadows to add depth & interest involves some planning. the style i used here requires treating the letters as if they have a definite thickness, which means they can't be woven over & under each other- it would ruin the 3D effect. another method would be to treat the letters like flat ribbons, which would allow weaving the elements together, then using 'drop shadows'. instead of the shadows being connected to the figures, drop shadows are detached, offset silhouettes which create an interesting floating effect. both styles have their charms.
Mitch, thanks for that explanation on shadows it kind of ties it all together in my head. You've done such an elegant job, the young man should be ecstatic.
