We spend ALL DAY, HOURS searching the beach when we go and leave with maybe a small baggy full each time. The first time I ever went I left feeling very let down, but now that I've been doing it for a few years now, I know it just takes patience.. I don't have much which is probably why I only get a little baggy full! lol :)
I have made many necklaces with the vials, but not just the glass. I know some people shine and polish the stones and make BEAUTIFUL pieces of jewelry with it.
