Iron-on patches, also known as embroidered patches, embroidered stickers, fabric patches, or heat transfer patches, are adhesive fabric patches designed for use on various fabric surfaces such as cotton, linen, and canvas. The back is coated with a heat-activated adhesive that melts when exposed to high temperatures, allowing it to be directly ironed onto the fabric. Once heated and adhered, the patches cannot be removed.

In the past, iron-on patches were primarily used for repairing holes or damage in clothing or sewn onto uniforms as badges. However, today, they have largely shifted to decorative purposes, allowing them to be applied to T-shirts, bags, fabric shoes, and hats, making accessories more unique!
