Crinkles are small wrinkles or ridges in a surface. There are several synonyms for the word crinkles such as creases, furrows, wrinkles, crumple, bend, fold, ripples, and waves. Creases are more structured and defined while wrinkles are more loosely defined and can appear on clothing or skin. Furrows are deeper ridges, often seen on the face of elderly people. Crumple means to compress something into a small, wrinkled shape. Bend and fold are used to describe objects that have been manipulated to cause crinkles in a specific spot. Finally, ripples and waves are undulating crinkles that occur on surfaces like water or fabric.
