Over 30 years ago my children and I made a Navity creche from salt dough and balsa wood. It had a place for the star at the top of the stable and my father (an electrician) made a small low watt light on the end of a fairly long cord to go behind the star hole. We still use the creche at Christmas, but now I use the light, taped under my sewing machine harp, to see what I'm sewing all year, and remember my sweet Dad everytime I see it.
