i used colored embrodery (sp) thread and croched a chain long enought to go around their necks. just keep watch as they get bigger to change them with the growth. you wouldn't need to crochet a chain, just use the thread.
I had them all ready before they were born. as each one came they got their thread. they were then refered to as green ,blue, pink and yellow until they got names.
