How do you add orderly wrinkles to faces?

Question

I want to add some wrinkles on the side faces of the lid like the left image

I'm a beginner so detailed explanation would be much appreciated. Thank you.

Answer 1

• If you want your lid to stay flat, so you can put a nice bevel on it, extrude the cylinder's cap-poly first. This will create a circular loop to hold that edge.

• Get enough separations in the side of the cylinder to hold your detail.

• Select the parts you want to push in, the "valleys". If you have a lot of those, after selecting the whole row of edges, use Mesh > Checker Deselect to get the pattern of selection, that you want

• Shrink/Fatten the faces in or out (Alt + S)or Extrude them into or out of the cylinder (E) by using Individual Origin as the Pivot Point.
