Unfortunately for graphic designers the world of AI is now making what traditionally took several meetings, some back and forth and maybe a couple of hundred bucks.  
AI can now make you a custom graphic that you can have on a sticker in about an hour. This opens up so much for what you can get from Sticker Mule.  The print quality the responsive nature the selection of the backing are now right at your phone. 
Amazing job super responsive company
