I love working with magnet paper. You can use it in a printer, but it is also fun to draw on. I took a sheet with me to York and drew up a set to use for the lost sheep story. It was inspired by Butterworth and Inkpen's story The Lost Sheep, though I added in dark shadowy places (like the godly play story). The boys loved listening to the story and Rowan especially loved telling it again and again hiding the lamb somewhere new each time.
I've drawn sets similar to this (but different stories) and copied it off on the magnet paper for kids to color and take home after church in the past, but haven't since leading godly play. I do love that kids can retell the story to parents and play with it on their own at home through the week. What do you think, is there room for a work a less open-ended option like this in a godly play setting?
