What my thoughts say about send a card
First of all, install graphic editing software like Photoshop in your computer. Good quality papers will be also required to print the card on the paper. Paper of different colors can be also used however; quality of paper is the most essential thing. You will also need a high quality printer such as Laser Jet Printer. After designing the card on the software you can also get it printed from the market because printers usually cost high and if you do not make custom cards regularly, then you should opt for market printing options.
