Okay, these look like pom-poms but that's still fabric right? I found these at http://www.imkeklee.com/ The lacy ribbon one below is also from Imkeklee as well.
I found this tutorial at http://www.chictopia.com/ It's called a T shirt necklace. Not sure if it's called that because it is made out of tee shirt fabric or you're supposed to wear it with a T shirt. Looks kind of busy doesn't it?
This one comes from http://www.shopruche.com/. Love it, love it love it!
