Basically you "Pin" things, images, to your "Boards" You could browse for hours on there looking at such cute, pretty, inspiring things.
You can also pin things from any website, with their bookmarklet and upload pics from your computer.
Here's my page . I've already been inspired to make a couple of DIY projects.
This ruffle pillow, I ran out of fabric and I don't have a sewing machine so don't make fun!
Also these paper roses. I just stuck it on the fridge like a little kid.
There's also lot's of pretty food and home pics, fashion, people, tons of stuff. They also have an app so you can pin things anywhere.
You can join by "requesting an invite" Which takes a while, I'm told, or I can invite you. Don't blame me when you can do little else!
