A couple years ago, I created this complete identity for a brand new company.
I basically had carte blanche, which is always nice, and it also helped that the client was easy to work with and well-organized.
I started off by establishing a "green living" vibe and colour scheme, then I went on to design the logo around this concept. Perhaps surprisingly, the logo's wordmark is not a font; it was actually made entirely from scratch using only circles and rectangles. A full suite of logos was created, including CMYK, RGB, PMS, black, greyscale and reverse versions. Finally, a logo master sheet PDF was created.
From there, a business card template and three double-sided 4x6 postcards were created using stock photos as well as images and logos gathered from various manufacturers and suppliers.
Here are the other two postcard backs.
