I, too, have a Pinterest account yet I, too, feel that it often offers my life about as much marginal utility as an eyebrow pencil. Just like Reddit doesn't have to be about strawman feminist memes and how much your parents oppress you by making you go to church that one time, Pinterest doesn't have to be about pinata cookies and melted crayon collages. But it is.
And CRAYON LIPSTICK. Like my lips can be any colour as soon as I get around to actually make it. And eyebrow pencils are the shit. Like, my hair is very pale so my eyebrows are invisible and they do so much for a face. Erhm... I think I'm starting to see your point.
Pinterest is the ultimate "wow that looks great but let's be honest: I won't be making it anytime soon" site. I mostly use it to look at nice things and think about aesthetic for when I eventually have nice things. That link is amazing, by the way.
Okay, since I'm from Sweden I think everyone should have made a gingerbread house during their childhood. We would make them in kindergarten every year when I was a kid. In the area where I live there is a big competition around a theme where people build amazing things.
