Share your appreciation (async).
Send one postcard per crewmember. Receive one postcard from each crewmember.
Each crewmember writes a postcard to each other member of the crew.
Decide on a date on which all the postcards should be sen (e.g. Dec 16th).
Everyone by themselves on their schedule (maybe offline).
Write each postcard as a thankyou-letter to your fellow crewmember. Tell that person what you like and value about them. Each postcard should send the message: "Thank you for being part of this crew!"
Take at least 5 minutes per postcard. But don't overthink it. Just write from your heart.
Postcards have two sides. One should hold your message. You could buy beautiful postcards or get some blank ones and create artworks of your own.
