In addition to varying scale, it's also important to mix the design
type as well. This is not to say that two or more geometric prints
can't work together, or two or more florals will spell disaster.
Rather, if you're feeling wary of your pattern-mixing skills,
combining a geometric print with a more floral or organic
design will usually be successful.
This one is probably a no brainer: if you want your series of patterns
to go together,
try to connect at least one color from one
item to the next.
This is not to say that each item has to feature
all the same colors, nor does it mean that every single color from
one pattern has to be represented somewhere in the room. But by
ensuring that each pattern in the room is connected to another,
somehow, they will all feel much more cohesive and coordinated.
