Isaiah 9:2 "The people who have walked in darkness have seen a great light..."
Isaiah 9 "Great Light" light switch plate
Plastic switch plates are really inexpensive and decorating them can make a great semi-permanent home reminder. Draw with permanent markers (instead of paint) or paint pens (if you have time and a blow dryer to hasten dry time) --leaving white areas to apply glow-in-the-dark paint (which illuminates brighter when it is placed on a white background). Write all of the phrase from the verse with pen, but apply some glow-in-the-dark paint around it.
The following image inspired my Isaiah 9 idea. Nice project, but the blue must have been painted ahead of time so it could be dry before the student wrote on it. Glow-in-the-dark stars are easy to find.
