 Chris here, and this is Sunday sharing. I'm here to share with you three main sketching techniques you need to know. Number one, scribbling. It's an excellent for capturing your core ideas and it gives you a holistic view of UI components. The second, layering. Layering focuses on the importance of the hierarchy before progressively building layers and elements and details. And finally, interactions. Interactions help you define the interaction in one sketch. You can easily change the placement of each interactive element without having to redraw everything.
