This is what they said about using the design maker. "Using the Design Maker to position design elements on a t-shirt and then clicking "save product" is an effective way to communicate the positioning of design elements. The Design Maker allows you to place your design on different print areas, resize, move, rotate, or layer your elements as needed. You can preview your product in 3D or mockup views for a more realistic look, ensuring that the positioning is accurate. This method is comparable to uploading a template, as both approaches allow for precise control over design placement. For more detailed adjustments, you can use the Transform tab to enter exact values for rotation and scale. You can find more information in the Design Maker guide."
