A big part of packaging and brand image for small companies is their stationary. The standard stickers they use to package up their products, the gift bags, business cards, letter heads and notebooks. To be successful it all needs to tie in, the theme, the colour scheme, the feel of the packaging and stationary itself.

This wedding invitation stationery is really adorable, with simple images and floral print it all pulls together nicely, despite the use of quite a few different colours.
