motorcycles is my life round patch is an embroidered iron on patch measuring 3.5x3.5 inch. Apply to your clothing by ironing or sewing it on. Please do not iron on patches to leather or nylon material. The patch features a nice embroidered die cut border making it easy to sew on when ironing on is not an option. Please remember using a household iron will not produce professional results. Both heat and pressure is required to adhere an iron on patch properly to a garment. We always recommend you sew on your patches.
