Ruffle

Ruffle is a decorative frill added to garments and textiles. In sewing, a ruffle is created by gathering or pleating a strip of fabric along one edge and attaching it to a garment, collar, sleeve, or hem. Ruffles can vary in width, fullness, and fabric weight, producing a draped or layered look. They appear in historical fashions—from the voluminous cuffs of the 18th century to contemporary blouses and dresses—and in home textiles such as curtains and pillow trims. Lace, chiffon, and lightweight cotton are common materials for ruffles.

As a verb, ruffle means to disturb or irritate, to disturb the smoothness or order of something. A breeze can ruffle a curtain or hair, and to ruffle someone's feathers is to upset or offend them. The term can also describe a roughened surface or a wrinkle, as in ruffled fabric.

In computing, Ruffle is an open-source emulator of Adobe Flash Player intended to run Flash content in modern environments. It aims to preserve access to SWF animations and games by recreating Flash functionality without the original plugin. Ruffle is available as a standalone application and as a browser extension, and it supports multiple platforms. The project provides a way to view legacy Flash content after Flash support ended.
