The quickest and simplest ways to use embroidery patches for clothes that you're using as a temporary adornment are with fabric glue or ironing. Heat activation of the sticky back of iron-on patches is required. There are some that have a backing sheet that must be taken off. An easy and practical substitute for stitching or ironing patches is to use fabric adhesive. Fabric glues are perfect for securing patches to different kinds of fabric since they form a stable and long-lasting bond.
