In my Sunday School class I did this with middle school age kids and they had a lot of fun. We covered a wall in paper and painted vines all over it, using brown, green, and purple paint and some inexpensive foam stamps of leaves and grapes. They just painted brown lines all over for the vine and branches and then added leaf and grape stamps everywhere. Then we took pictures of all of the kids in the church and glued their photos on all the branches.
