We have created templates for all of our products that you can download and edit with Photoshop to create your designs.
Each template is listed in the below table
With each template you will find a detailed video showing you how to use it, and any design tips for each particular product. If you do not have Photoshop you can still create designs using which ever graphics software you choose.
Make sure your image is created to the exact dimensions given and saved as a JPEG in RGB format.
