There are different shapes to use. You can use a logo for your company, promotional items such as pens, mugs, promotional calendars, banners, and t_shirts. The variety of shapes and sizes is what makes your designs unique.
For example, a free_flyer design template that uses an image of your company's logo and text in red can tell you that your company is popular. In a case like this, a red color can stand out on the flyer. The same information can be found with a description in blue or yellow.
