I want to design a digital invitation using graphics with a premium license. I would plan to alter the graphic to make it transformative and flatten the image so that no individual pieces could be manipulated. Then sell the invitation file on Etsy, for example. Would I then be able to upload this digital invitation file to Corjl or Templett and let the customer edit the text only (using a non design bundles text)? Would this be allowed with the premium license or would I need to purchase the commercial license for the graphics used to create the invitation?
