Thanks! I just used Adobe Illustrator- I am a graphic designer so I'm in that software every day, but I was just a few days ago starting to research other tools to build this kind of thing that could open the process up to collaboration. Would love to build this online and be able to embed it, but I still need to search around to see if the right tool exists. It would be hard for me to give up the free design reign and flexibility I have with Adobe.
