Sketching your ideas before moving on to the computer is important for many reasons:
Sketching allows designers to freely try different ideas or go in other directions without the constraints of digital tools. You can produce multiple ideas and solutions on paper first.
Suppose you first sketch your thoughts into forms on paper. This helps “visualize” different layout ideas and visual items you may want to add before committing to a specific design.
You can quickly sketch out different versions and make any adjustments on paper. Also, do multiple comparisons to decide the route you want to take.
Sketching stimulates creativity and allows more organic ideas to emerge. Many times, it pushes the designer to think outside the box.
One of the most important reasons to sketch first is your sketches can serve as a communication tool. You can share this with other designers, team members, or clients to show a clear representation of the design early in the process to ensure you bring a fantastic design to the table that the client loves.
