I got the colored chain at hobby lobby and two large charms there, the gold bicycle and large black glasses, as well as two packs of miniature, bright colored Christmas ornaments. I bought two pairs of earrings at Claire's that I took apart for smaller bright colored charms, and the rest is either from my shadow boxes of cute mini things, or pieces of my kids toys or game pieces.
I love the end result, it's fun and playful and I had quite a few compliments on it last night, even strangers who were mildly obsessed with it. LOL. It's not superheavy since most of it is plastic. The funny part is, I still have enough stuff that I could probably make an entire other necklace! LOL
Did you have one as a kid?
