DIY Nursing or Teething Necklace

I know, I know... all of my crafting lately has been centered around a certain roommate that moved in a couple of months ago. It's my life right now, OK? In any event, I was looking to order a couple of teething necklaces from Etsy or one of those other sites but after I started looking at them and some of the prices, I decided I could make myself and some of my nursing mothers each a necklace for less than one of the online versions. Mine may not be as perfect but they are satisfyingly pretty and I have to say they are pretty simple to whip up!
