Hmmm. NO metal? A cloth necklace sounds gorgeous. Or how about beaded necklaces/bracelets with the beads strung on some form of string rather than metal chains? Or wood (I have a couple of wood pendants on string, and there are also wooden beads), or chunky glass pendants. You can often get necklaces like these at craft shows/booths. As for scarves, you may be able to wrap them a different way and change the emphasis -- for example, loop an infinity scarf around the neck so all the attention is brought up to your face, or let the ends hang straight down without wrapping even once.
