I think giving someone a handmade card is one of the best things you can do. It is meaningful and special. It is also an opportunity to express how you feel about this person. I have friends who are a couple and they pray for me every day. I give them a lot of cards to express how I feel grateful for their prayers and their friendship.
All my friends have received a card from me from time to time. Its something I do to tell people that they mean a lot to me. I encourage you to grab some card stock, paper and some glue and scissors. Make a card and send it to someone who needs some encouragement.
