You will use a random assortment of papers, memo sheets, cards, stationary, etc. (whatever you have laying around) to write a letter to 2 partners. There is no minimum amount required, but make sure you write enough to develop a letter of substance. You can talk about your day, all about yourself, vent, etc. Use whatever markers, pens, inks, etc. you have around your home. Perhaps you have a pen that's on its last leg? Include one or two flat tuck-ins, senders choice, for your partners.

Easy peasy! Happy swapping!
