how to remove a blank layer from the view

[emh]

I have an item that I only want to print on one side, a glass, but there is also a back layer. How can I remove the back layer from the listing?

You cannot remove areas designated as printable by Zazzle. You do not, however, have to fill them. You may get a warning when you publish, but you won’t be prevented from doing so.
