My son was gifted in pottery, and I have his work in my living room. I also have a beautiful watercolor he did of Mt. Rainier. You can bet I'll never tire of these items. Group your collections on your wall. Let your home reflect your personality.
Some people like to display pictures of their ancestors.
Spend your money on things that will last. Remember, when you put up wallpaper, you will probably have to leave it someday. However, your pictures and collectibles will go with you wherever you go.
