Hey! I'm Randolph, and I run The Paper Prototype Company.
I really don't have any art skills but I love design, especially sketching.It's awesome starting designs on paper because it's the fastest way to get ideas out into the open.
One annoying part of paper prototypes is drawing rectangles over and over again to represent phone screens. One day, after drawing about 50 of these phones, it dawned on me that I could save a lot of time by just printing out a bunch at once.
Pretty simple idea, but they've been really helpful to me as a designer. Would love to hear what you think! Feel free to shoot me an email at email@example.com
