I love this Adler pillow. It would make a great stand-in in a room like this one from Southern Accents, despite the fact that this room's vibe is a little more organic than geometric.
The idea with decorating is that you don't need to follow the stylists lockstep. Choose what you like. Be willing to find a fabric remnant on eBay and use it for a pillow... or have one fashioned out of a sheet found at Target.
The 2 yards of linen fabric are another great alternative.
