I used a "J" hook and a shell in shell crochet stitch. Crochet Geek made a great video with instructions on how to do the shell stitch (and end up with a scarf!) -- click HERE. I edged the shawl with a simple 5 double crochet shell. I strung the coral and turquoise necklaces at a 30" and 28" lengths and loved how they looked together. However, when I wore them, they were too heavy to be comfortable, so I need to re-string them.
