Now I show you my personal version of a Poket Letter.
What is a Pocket Letter? Essentially, you fill all the pockets of your 9-Pocket-Trading Card Protector. Then you send the whole page to someone who wants to swap his/hers with yours.
You can fill the pockets with whatever you like (stickers, tea bags, a note, washi tape samples, pictures, etc.). A short message or letter is included and tucked in one of the pockets.
Here's what I've created:
Saffron Honey Cardstock
Azure Bike Die-Cuts
Baby Boy Little Friends
Dew Dew Glue
