The Rule of Threes
The rule of threes states that “things that come in threes are funnier, more satisfying, or more effective than other numbers of things”, and this is most definitely true in decorating.
Anytime you’re creating a display or hanging multiple items, notice how groupings of three just feel right. This isn’t limited to just the number three – it applies to all odd numbers. So if you have multiple items you want to use, bump up the number to 5, 7, or 9.
