If I create two layers and put some shapes in Layer A and other shapes in Layer B I understand how to put Layer A "behind" Layer B and vice-versa.
But some of my shapes are in Layer X and others are in "Page". Is there a way to put Layer X *behind* Page? I can make Layer X invisible or put it in front of Page but I haven't figured out how to put it behind Page.
My goal is to keep 99% of my shapes in "Page" and then use a background layer to create a colorful background. Obviously this won't work if the background isn't "behind" the shapes.
Thanks!
