Stickers, such as Sublidecal, work great for branding when you cannot sublimate directly onto the product. You can purchase sticker material in sheets or rolls so that you can sublimate your business information, whatever size you like, and print and sublimate a whole sheet out at a time. Then you can put these on the back of plaques, photo panels, or the bottom of wood boxes.
