The mock-up allows you to see a preview of your custom apparel as you customize it. Please note that this preview is not an exact representation and is meant only to give you a general idea of the result.
We have standard locations for decoration (e.g., left/right chest areas, back, under the back collar) that may vary slightly from what you see in your product preview.
Our production team will always work to make sure your design looks its best on the custom apparel products you order. Slight deviations between the preview we sent to you and your final product should not be considered errors.
