Throw pillows are one of the cheapest and chicest ways to makeover a space in your home. But there is absolutely an art to layering them so that you achieve the perfect marriage of function and form, according to HGTV host and interior designer Genevieve Gorder .

"I think we've kind of OD'd a bit on decorative pillows to the point where you couldn't even see the bed. Like it was comical," Gorder told The Huffington Post. "I think it is important to think about function -- that is what makes great design great."

They're also extremely versatile. "Pillows, more than anything else you put into a room, are easy to switch out, so you can change the look and color palette," says AphroChic founder Bryan Mason.
