Two sample quilt layouts shown below illustrate the variety of options you can use to make a striking quilt by rotating some or many of the blocks.

The quilt layout featured on the left sets the blocks side by side and creates a look of perpetual motion across the quilt creating endless "waves".

The quilt layout illustrated on the right also sets the blocks side by side, but uses 90 or 180 degree rotations of some of the blocks to create a secondary design.
