Before i start working on a new project i usually sketch everything out before i begin. I use a regular sketchbook that is specifically made for drawing. But it’s annoying not being able to draw perfectly strait lines and such, even with a ruler. So i’m wondering if anyone knows any excellent sketchbooks that are specifically made for Web Designers/UI Designers. I used Google and found a few interesting sketchbooks but nothing that i would pay for. So i’m asking if anyone knows any amazing sketchbooks that are used for designing UI/web pages.
