Boards are where you save your Pins. Think of boards as folders. Any Pins you find that you like and want to save, you will save them to the board that is relevant to the Pin topic. This also makes it easier for others to find your boards and the related pins.
You can make boards for anything and everything—save recipes to your Breakfast Recipes board, saved fashion ideas to your Workwear Fashion board and more.
There are different types of Boards
A public board is searchable and visible to everyone.
A secret board is not visible to others visiting your profile. However, you can add collaborators to your secret board. These people will have access to all of the content within the secret board.
You have the option to add collaborators to your board. Anyone who becomes a collaborator will be able to add pins to your board.
