if you're from the eighties.

then you must know the friendship bracelet. i used to know how to make one. when i was in junior high, we all went to venice and i got my hair braided with this (only one strand, though)!
so i squaled in joy when i found out that if you make one longer, it can actually be worn as necklace! see the tutorial over at honestly...wtf, found via poppytalk. talk about good old days, eh?
