I have a hard time finding black flats I like, that are not so detailed and/or specific that I cannot wear it with many outfits or so plain and boring that I hate them, so I might try this out and see, It's like owning a bunch of shoes, but not really. Bedazzle your shoes, LOL!!
I know this isn't exactly DIY, but it's cool, right! Fashion is so much fun and this allows you to play around with it instead of searching the Internet, boutiques, etc for THAT shoe!!
