From my research, it looks like there are two strong directions you can go with your butterfly wedding. You can either go with the DIY look and have brightly colored, whimsical, hand cut paper butterflies as seen in the top image (above).
The second direction is to go realistic with your butterfly accents and go with earth toned or bright colored butterflies. I always think about butterflies as a summer detail, but was happy to find some really beautiful fall inspiration with accents of butterflies. The warm coloring of many butterflies lends itself to a fall wedding color palette.
