When choosing pillows for layering remember the following:
SCALE - COLOR - PRINT
Too many big shapes for too many tiny prints on top of each other are too hard
on the eyes. Ensure you scale down patterns. Think Large, Medium, Small.
Make sure you choose a grounding color, you can start with a solid block color,
the start building patterns incorporating this ground color.
Do not be afraid of pattern. Mixing patterns can add a touch of the unexpected.
