Here are some samples of cards and pocket Scripture books I made for our soldiers stationed overseas. Of course there is a message of appreciation in every card. Since I'm inside most of the time with Covid, it's a great way to spend my time doing something constructive. Since I make so many, I usually do them on my PC.
I take them to Military Missions in Lexington, Ky and they send them where needed. They are always needing thank you cards. This is a great project for a Sunday School class or a Scout Troop. You can check out their Face Book page for more things needed. And of course monetary donations are appreciated, too. Everything is tax deductible.
