Come see a "Hand hammered" sterling blanket pin

I'd just try to make sure that you've sanded/polished it as smooth as possible...

Na'er ye worry! the wire was well smoothed with 0000 steel wool before tarnishing, then sanded with 1500 grit emery paper.
After working (with leather padded pliers), I sanded again to make sure there were no snag points to be found.
I paid special attention to making sure the point of the pin was thin, but round, so it would push between yarns rather than through them.
