Plaid Floors from Christy Ferer's book, "Decorating on a Dime"

Christy Ferer (Vidicom CEO) recommends measuring the floor and order equal amounts of your four colors. The first color should be dense, like the dark green in our photo. The second color is the same color value, but half the density of the first color. (In the photo this is pale green.) The third color is the same density as the second (pale blue in the picture), but a compatible color to the first two. (just like the pale pink is to lavender of pale yellow to pale peach.) The fourth color is white. She says to lay out your pattern beginning in the most visible corner of the room. Wait to glue until you have set out your pattern.
