. Just couldn't get in to it.
I'm using it for "ideas" - I like to do a lot of DIY home improvement, and it's really nice for finding pictures. For instance, I want to redo our weird stairs - they are painted off white, with industrial rubber "slip guards" and then the walls are 3 different kinds of wall paper. I search pinterest for "stairs" or "painted stairs" or "stairwells", and browse the pictures - when I see something I might like, I "pin" it to a folder, and keep on looking. Then, I can go to the folder, and look at all the ones I pinned, and see from there what I want to do (which right now I'm thinking of taking off the slip guards, and then painting a stripe like runner along it, and have some ideas for painting to make it look roomier - the stairway is really narrow).
