Changing your patch design is possible, but only before approving the design proof. Switching between embroidery, woven, or sublimated designs is possible, depending on clarity needs. Changes from fabric to PVC or leather patches will incur fees due to their mold-based production. Minor adjustments like color changes are manageable without significant delays. We'll issue a new invoice for added costs or refund for reduced costs. However, please keep in mind that frequent changes may cause delays to your project.
