I just love the idea of a quote wall! You can make the walls of your office, family room, or even your dining room reflect your interests and core values, using author quotes, inspirational quotes, etc. You can switch them around at different times of the year (like the holidays! How cute would a dining room accent wall of "thankful" quotes be at Thanksgiving?).
You can use framed quotes, wall decals, or if you are artistic you can freehand. Add some quotes of your own! Have your kids contribute and you can build it into a family tree of quotes and family sayings!
