Mixing patterns can be tricky—you don't want to overwhelm the eye or make your space look too chaotic—so follow these few, simple guidelines to make sure that your pattern-mixing looks lively and not loony.
1. Pick a palette
If your pattern mixing falls within a color palette that is repeated throughout the space, the patterns won't compete with one another; they will work together to create a cohesive look.
2. Mix big patterns with small patterns
If you have too many types of big patterns, or too many types small patterns, they start to look messy. But if you create a good balance of large patterns contrasted with small patterns, the eye can more easily differentiate the two and it looks more relaxed.
3. Add neutrals
If you have a lot of pattern going on in a room, consider leaving the walls a more neutral color. This way, the walls will act as a 'frame' for all of your pattern mixing.
4. Add solids to the mix
Be sure to have solid chunks of color too—if you have a bunch of patterned throw pillows, add a few solid pillows in the mix so that the patterns can really pop!
