Three architecture students from Columbia University have developed a notebook specially designed with architects in mind. The notebook has 130 pages of ready to be drawn on pages with lightly dotted grids at 4 different scales 1:200, 1:100, 1:50 & 1:25. It is the only notebook with all 4 scales. It also exists in metric and imperial editions.
Order on A:LOG or check out their Kickstarter page to support them.
I have recently found this very affordable version of the same principle and it comes in loads of different colours. Enjoy.
