Sustana is an industry-leading American producer of fibre-based products and services that places sustainability at the heart of what it does. Collins designed a logo that fold and rolls a single sheet of paper into concentric ‘S’. The weighting of the line, not mono-linear, ties it nicely to a custom drawn reverse stress typeface. This lends it a somewhat calligraphic quality that suggests care and craft, and lends the logo further distinction.
