To design cards for Thanksgiving, begin with a high-resolution image in the public domain and use image design software to manipulate the canvas to include back matter. On a separate canvas, create an inside greeting for your card. Print these two images on reverse sides of quality card stock (ensuring that you have them correctly oriented so that everything is facing the right way up), and the result will be a professional-looking card. You can decorate with ribbons, glitter glue, or pinking scissors for a more homely look.
