Here is a Christmas tree found at a veterans hospital. They used a flocked green tree and covered it with flags and red and blue ornaments. Service members boots were put to the base of the tree. A collection of flags were used to make a finial on top of the tree. White lights are used but i think I would add some red and blue as well. Making a statement like this is so respectful and very beautiful to boot.
