You should def. use deadsoft when wrapping a pendant. I actually just wrapped a piece of sea glass for my aunts xmas gift,came out beautiful. I used 22 gauge Square Dead Soft Argentium Silver,another type of sterling.The big advantage of using sterling or sterling fill too is that you can tumble your piece after and harden,shine and smooth the wire.Good luck with your transition...just remember to practice in copper-I learned that the hard way =/
