2. Again, prop three European shams along the back of the bed. Instead of king size pillows, use three queen or standard size pillows with shams for the second layer, then center two boudoir pillows on the gaps. (Note that European squares often coordinate with the duvet in terms of color and pattern.). 3. Begin with the same trio of European shams in the back. Add a pair of king size pillows in king size shams. Finish with 20-inch-by-20-inch decorative pillows centered in front of the two king size shams.
