wrinkles, creases, folds
皺 centers on surface irregularities that disrupt smoothness: wrinkles, creases, and folds, especially on skin or fabric.
皺 combines 芻 (likely a phonetic element) with 皮 (skin), suggesting wrinkles or creases on skin. The exact historical development of the left component is uncertain.
The left side 芻 looks like a bundle of tangled grass, and the right side 皮 means skin. Imagine skin becoming as creased and folded as a twisted bundle of grass.
For シュウ, picture a wrinkled shirt you need to iron: 'shoo' away the wrinkles with an iron. 'Shoo' -> シュウ, and the shirt becomes smooth.
