Here is an idea to make a festive memorial day centerpiece.
1 white metal vase
bunch of fresh or silk flowers (I used silks) in red, yellow white and blue
American Flags



Then you can use white dishes with white napkins and bring in the color with a red silk flower and tuck in the silverware underneath. I also used red salad plates to bring in more color and put it all on denim fabric for a table cloth.
