A collection of icons specially made for Plimsoll based on a rather unusual 26 pixel grid.

Rough design rules

• No faux 3D. Make icons flat and two dimensional.
• Outlined style. No heavy fills.
• Use a 26×26 grid for layout. Vertically and horizontally centre any icons that don't cleanly fill the grid.
• Use a consistent stroke width of 2px.
• Use a border radius of 3px where necessary.
• Leave a space of at least 2px between parallel lines, so they don't get lost when shrunk down.
