Here in Korea I often find cute accessories, but put together in such a way that I would never wear them. A few days ago I found a cute wooden bunny thingy attached to a hairband - I wouldn't wear it like that, but I loved the bunny. I thought it cost 1000won (close to 1 dollar/7rand) when I went to pay the shop assistant irritatedly sent me back to the shelf - saying it was 1000won for 2. YAY ME!! so I bought two wooden thingies attached to hairbands.
Anyway - to make a long story short, I changed them into brooches, it took me about 5 minutes. ^.^
Step 1: get a brooch pin
Step 2: detach elastic band (it was stuck on surprisingly well)
Step 3: Glue the brooch pin to the back (I used a glue gun - I LOVE glue guns)
Step 4: TA DA!!
I hope you find some great CHEAP stuff to revamp.
