Cutting out shapes on a layer
I want to make a template that consists of a number of circle shapes that are cut out of a black layer. The idea is to be able to sandwich images between the cut out template layer windows and the background. I have the the background layer as white, the next layer is black and then I have a lot of layers with a circle shape on each one. I cannot figure out how to cut those circle shapes out of the black layer. Would love some help.
