Creating a raised stamp

Hi There, I need some help please please please. I am trying to raise the design on the stamp, but not on the base stamp itself. How do I this please I have attached a pic to help better explain. Thanks heaps

If you are trying to raise the stamp but not the outline, click “delete outer edge” and that will get rid of it.

Hi Nathan, thanks for responding. I dont think I explained myself well enough. I would like my back to be no more than 3mm and any image that I choose to make a stamp with about 9mm, so that the combined image and base is raised to 12mm. I am just lost as to what settings to use. I have played and played and I just get the image to raise only 9mm or the base only 3mm
can you guide me please in the right direction - thankyou Debbie
