Business Card Design Brief
Hi,
I need a coffee loyalty card designed - one where you can stamp a section each time a customer buys a coffee - then they get the tenth coffee free.
So on one side of the card we need an area to stamp, and on the other side we need our business details.
I have uploaded some loyalty card designs I like, for some ideas, and I have uploaded our logo and details.
