Its another part of scrapbooking but on a much smaller, less overwhelming procedure. Its a way to connect with people all over the world and basically you are to give little bits and pieces to them of your personality but yet of things that appeal to them. There are groups on facebook just for this, there is a whole network to sign up with people to swap pocket letters with.
Basically you pair up with someone that may have a similar taste as you and you share a little letter about yourself, each pocket houses things like stickers, twine, sequins, paperclips etc.
I am really into planners right now so my pocket letter "goodies" were centered around what a planner would love. The pages themselves or cards are something someone could re-use for a little "photo" themed pocket page or even to use on a layout or something.
I used "Oh Snap" stamp set from Bella Creationz and each pocket has various items that are found in the store also.
