Rimple is a type of decorative fabric trimming that is used to embellish clothing and other fabrics. It is made up of two components: a FOLD and a FURROW. The FOLD is a four-letter word meaning to bend or double over, while the FURROW is a six-letter word meaning a long narrow groove or channel. Together, these two components create a decorative trimming that can be used to add texture and interest to any fabric.
