Navy Blue Placemats

navy blue
Navy blue is a very dark shade of the color blue which almost appears as black. Navy blue got its name from the dark blue (contrasted with white) worn by officers in the British Royal Navy since 1748 and subsequently adopted by other navies around the world.
"Navy Blue" is the name of a song written by Bob Crewe, Bud Rehak and Eddie Rambeau. The song tells the story of a girl who was lonely for her steady boyfriend while he was away from home in the U.S. Navy and could hardly wait to see him again.

placemats
A placemat is a protective table pad usually made of paper, plastic or cloth for restaurants and households. Asian-style placemats may feature thin slats of bamboo or colourful beads. The term is derived from the mat being put at a person's "place" (chair) at a table.
