Looking for an idea to sell a different product type the back-the-school market? Try printing on cork board!
You can use your DTG printer to print CMYK inks directly on to the cork board to create personalize note / bulletin boards to students. Most craft stores will sell the coward board material at a pretty cheap price and then add a simple frame to it to make it look nice. Below is a video showing the cork board being printed on a Brother GT-3 printer.
