The bed below illustrates the pillow sizes. The back row, closest to the headboard, are European-sized pillows. Because they are taller than standard pillows, they are perfect for the back row. Next, a pillow several inches shorter than the Euro pillow permits the back pillow to be visible. In front, of that pillow is a standard pillow. (Choose a standard, queen, or king width depending on your bed.) Finally, front and center is the narrowest pillow or pillows. For this row, you can use two boudoir pillows or a custom made long pillow to bridge the others.
Next, the duvet is folded in half and covers the lower third of the bed. Often a smaller throw is tossed across the bed or left on the bench at the foot of the bed.
I must confess, I have been influenced by advertising, but haven't succumbed completely. I put pillows at the top of our bed, a feather duvet at the foot of the bed, and a dust ruffle that touches the floor. However, I have "cheaped-out" on the number of pillows and don't have a cashmere throw. What about you? Have you been conditioned to feather your nest like the beds shown here?
