1. Print the cards
Go to a printable page such as for Cabo Rush and print. Each card is designed to be poker card size (2.5" by 3.5" or 63.5mm by 88.9mm) so measure that you've printed to scale. Each card is also designed to have a front and a back - consider printing the pages double sided (flip along the short edge if your printer supports that).
2. Cut the cards
Cut the cards out as best as you can. A pair of scissors will get the job done, but a guillotine is better.
3. Round the corners
Consider rounding the corners of the paper to make it look more professional.
4. Sleeving the cards
Consider putting the cards in a protector.
5. Play the game
Enjoy playing!
