At our church, we have a quilt ministry. There is always a quilt that is finished and ready to go. By finished I mean layered with binding on and thread for ties where they need to be. We consecrate the quilt and pray for the designated recipient during the church service. After the service and for the next week, people can knot the threads as they say a prayer for the recipient. There is a spiral booklet (could just be a stapled one) next to the quilt where people sign their names and write personal messages to the recipient. After the week is done, any untied threads are tied and the person closest to the sick/injured person takes the quilt with the book to them.
I like this way because there's always a quilt available for emergencies and the booklet is small, but contains all the names and kind messages.
