The large proportion of solid color areas will balance the smaller areas of various prints. Do not combine two floral prints that are similar in size in the same room. A small floral print can be combined with a large floral print if the two have similar colors. If the room is small, combine prints that are color related and use solid colors for the background area. Solid colors on the walls and floor and low contrast in color of prints will make the room look larger.
Stripes work almost as a solid.
They can mix with florals, geometrics, and plaids, but do not use all the patterns together. Avoid clustering all of your patterns in the same area. Clustering would give one area too much weight and create an unbalanced effect. Distribute the patterns around the room. If the pattern on the floor is a busy one, everything else in the room should be plain or textured.
