People from all over the world go on Pinterest and post pictures that they find interesting. It is like having a little picture blog. You can re"pin" pictures, if you see a picture that you like, you reblog it (or in this case, repin it). Pinterest if mostly about drawing and art. Most paintings and drawings on there have tutorials, and they are really cool and really fun to do !! But there are other categories on Pinterest, too.
Anyways, Pinterest is online at a computer and is also an app.
pinterest is a website/app where you can create different "pinboards." these are places where you store different things that you see on pinterest. there are links for crafts, food recipes, houses, wedding decor, etc. you "pin" these things on the boards so that you can go back and see them later. if you click on your pin, it will take you to a website where you can get the recipe or buy the product. sign up and it's self explanatory from there!
