[header] How to iron on a patch [title] Figure out what type of patch you have. [step] Some patches come with glue on the back, and others simply have a cloth backing. Take a close look at your patch and decide whether you may need additional materials. <sep> (A) [substeps] If your patch's backing is rotten, use a glue stick to remove the patch. If you've got an iron, use it to remove gunk that can build up. (B) [title] Try to get a patch with a slightly bigger border. [step] Some stains go away over time, so this method is especially useful if your patch is intended for a horizontal application. (C) [substeps] Patches sold with glue on them can be packed and cropped. Depending on the size of your patch, you may want to use about three sheets of 1/4-inch (0.3 cm) fabric, or just three standard strips. (D) [substeps] Decorative embroidered fabric patches are usually thick, stiff, and have what looks like plastic glue on one side. These can be used to cover ripped or discolored fabric.
