What you will get

Twelve line icons for your theme in a 4x3 grid, all with the same 2px rounded stroke, one colour on white, matching size and spacing and no text.

Common mistake

Some icons are filled while others are outlines.

Fix: Add “outline only, no filled shapes” after the stroke rule, and regenerate the odd ones on their own with the same wording.

Also watch for

The icons cannot be used as they are in an app. The result is a picture, not vector files. Trace them in a vector editor, or use them as a brief for a designer.
Two icons look almost the same. Name very different objects in the list, such as a suitcase and a map, not a bag and a backpack.

Try a variation: make a duotone set

Ask for the same icons with a soft second colour as a small filled shape behind each line drawing.

Keep the same stroke width, grid and corner style. Make the next twelve icons for [NEW THEME] so the two sets match.
