Frontprint & Backprint on a product

Sorry if this is a duplicate, couldn’t find one like it.

If I wanted to put one design on the front, and another different design on the back, how do I do that?

sorry for the dumb question I’m dumb new.

First, upload both designs independently as normal designs. no need to publish it.

Then, click on the upload button in the design area and in the popup, at the bottom there is an option to create a product with multiple designs.

ah ok
thanks!
