This is good for Easter or any time when you have talked about the resurrection.
We talked about Jesus dying and rising again to new life and the hope that this gives us. The children were then encouraged to think of areas in their life where they'd like to have a new start- maybe in a relationship where they'd argued with someone, or something positive that they'd like to start doing. They then coloured in part of a butterfly's wings as a symbol of asking God to help them with that new start (you can find lots of outline pictures of butterflies on the internet. We just printed one out and enlarged it to A3 size). Some of them shared and others kept it private. This has now become one of our regular prayer stations.
