I've spent hours browsing people's pins. I repin beautiful ideas. I create boards to organize my obsessions. I am THRILLED when someone finds my discoveries repin-worthy.
It's a great way to figure out your style. And your friends' styles. Or, as my friend noted, a way for your husband to learn your style.
Anyway, go check out Pinterest. You won't regret it. Your husband may stage an intervention, though.
