Large patches are here → #DOCKROCK Large Patches Other biker (motorcycle-related) items are here → #BIKER Other G-jackets and T-shirts can be attached with a steam iron (sewing is ideal). If you don't have a steam iron, wet a handkerchief with water and press it onto the patch. Do not touch it until it is completely dry. For leather jackets and leather vests, sewing is better, but leather adhesive sold at home centers is also acceptable. Do not use on fabrics that will melt with an iron. If you want to change the patch design depending on the day, you can also attach them with Velcro (available at home centers). 28X18cm
