First, if you do not have access yet to this manufacturer, you can reach out to help@mtm.design to set up your account for access. You will also need the most recent set of fabrics & trims from Stoyan.
When this has been done, you will now see Polo and T-Shirt as a garment style to select from the builder (after choosing Add new item from a cart).
The builder will function similarly to the dress shirt, starting with the fabric selection. Simply enter the fabric number you wish to use and then follow each design option by hitting "Next".
Important --> when you select a design feature, "Make a selection" will change to the feature you've selected.
For the measurements, you simply need to input finished measurements in the Sport Shirt measurement tab on the normal measurement page.
