Uniformity begets recognition. This is the strategy of companies and organizations who let their employees and members wear custom made patches. It is one way of being recognized outside of their organization. Patches are less expensive than uniforms. They are smaller and therefore easier to customize.
There are companies whose business is to make customized patches. They can make it in any shape, color and design. They can provide the customer with a pre-set design customizing it with a logo or text. They can also work with the customer to make a design from scratch. Whichever the customer choose it will be to the benefit of his business.
