This is a vintage piece of cotton broadcloth which was left from making a garment. In addition to the blues, white and green, the background is a light lavender, lavender-gray color. 

The piece is 1 and 1/4 yards long plus some extra angles and 35 inches wide. It is a medium weight broadcloth, which would work well for quilting, crafts or a small sewing project. 

It is from my mother's fabric stash.
