Getting better. How often are you sketching? In what medium?
Try sketching a minimum of 10 pages per day. Try sketching around a theme each day (ie watches one day, dishwashers the next, followed by to go coffee cups…)
Also try switching you mediums up. Try to sketch only with a black sharpie for a week. Then only with a blue pencil for a week.
Lastly, when you see things out in the world, try to imagine what the designer’s sketch looked like for that product. How would that person communicate the idea?
