friendship bracelet nostalgia

So, while I was browsing the internet last night, I came across an awesome post on making friendship bracelets. You know.. the ones we all used to make back in school all year and trade with our friends? Seriously... I carried the whole stuff colourfuls thread with me to school, and of course scissors but not some cool-looking beads as in trends nowadays. My friends and I would make them on recess ( bagi aku satu oi...aku nak satu ...aku nak...lepas sorang sorang... I miss those days!), and swap them. Before too long, we would have 5-10 on and it used to be our kinda cool bracelet....

What happened to these, really? Why did it take so long for these to come back around?
