We've used this chart for 6 years. We've added to our family, so I'm letting go, but I thought I'd put up a tutorial.
What you need:
Two pieces of paper
Self adhesive Velcro
Draw whatever you want to to represent your family/household. Make icons for the different activities that you would like to have happen at your Family Home Evening. Make sure they coincide with the number of people in your family. Color it! Then, make name tags for each person. Make sure there is room on your drawing to put the names and still see the drawing and icons. Laminate everything. Cut it out. Apply the Velcro!
That's it. Super cheap.
If you have a laminator and Velcro this chart could be free!
