Sandwich Hem

A sandwich hem is created by enclosing the raw edge of a garment between two layers of fabric or facing. This technique hides the cut edge completely, producing a clean and reversible finish. It adds weight and structure to the garment, making it ideal for hems on skirts, dresses, and reversible styles. Because the edge is trapped between fabric layers, it prevents fraying and provides a polished, high-quality appearance both inside and out.
