Canva is a great marketing tool to create graphics for social media. I have created a free template for farm fresh eggs that you can use.
This template is designed to fit a 4x6 thermal shipping label. 3 labels will fit nicely.
If you are looking for a thermal printer I recommend the Rollo Thermal Printer.
