"Double fold" refers to a technique used in various contexts, such as cooking and textiles. In cooking, it often describes the method of folding dough or batter over itself twice to create layers, enhancing texture and flavor. This technique is commonly seen in pastries like croissants, where the dough is folded multiple times to create flaky layers. In textiles, "double fold" can refer to a way of finishing the edges of fabric. This involves folding the fabric over itself twice to create a clean, finished edge that prevents fraying. This method is often used in sewing projects to ensure durability and a polished appearance.
