Each day this week, sketch a round product: something that’s clearly based on a cylinder, a sphere, or a cone. The whole product doesn’t need to be round, but a large part of it should be.

As you sketch, pay special attention to how the round parts affect the rest of the product. Start with these questions:

  • How do the round parts connect to the rest of the product? Are they a single piece, with round shapes blending seamlessly into other shapes? Are they separate parts? Are there parting lines? Gaps?
  • What happens to details, like text, logos, parting lines or seams, on the surface of the product? How do they curve to follow the surface?

If your product is too complicated to finish in a single 30 minute session, try breaking it up. Draw a simple form study (where you simplify everything into boxes, cylinders, spheres, and cones) on one day. Then sketch interesting details on another day.

Here are some round products you could use for this prompt:

  • A set of headphones with round earpieces
  • A water bottle
  • A claw hammer
  • A hat
  • An oscillating fan
  • A combination lock
  • A steering wheel


Here’s how it works

New sketch prompts will appear every Monday throughout the summer. Each week will have 6 sketch prompts that focus on a theme. Pick one sketch prompt and do one 20-30 minute sketch every day, 6 days a week. Then take a day off and start again with the next weeks’ post.
