Each year I make 150 Christmas cards for my church. The church sends them out to members of our congregation, with a photocopied list of people of contributed to the project (the money goes to the church - I donate the cards) and a message from the pastors. 

This Pinterest board shows some of the designs I've used over the years. I usually make 24 of one design, so that I get a good mixture of the fun of designing, and the efficiency of assembly-line work!
