Everyone wants an awesome looking cover for their RPG. It grabs people the moment they open your PDF, and sets the tone for everything that follows. A huge part of a great cover is the artwork, which is beyond the scope of this post, but a cover is more than just artwork, you need your text in there as well. For this, Google Drawings works very well. It’s a part of Google Drive, just go to New->More->Google Drawings. I’ll write a separate post about google drawings, as I think it’s a pretty great tool for designers.
