♥ Let's begin! ♥
Open your program. A page will automatically pop up but, since I want to show you how to add layers, I will create a new canvas and re-size my papers in smaller sizes so you can see this better.
As you can tell from below, I have three NEW paper sizes and one WHITE background (giving me a total of FOUR layers).
Making sure that you have the layer you wish to move highlighted in BLUE (as seen below), highlight the arrow indicating "Move Layer Down" and click once.
