I do this too, Grannywin. I use an English A5 size, which I print on the front then re-feed through the printer and print the inside.
I store a card template in the template section that I use whenever I want to create a card.
I'm pretty certain that I left a template on the Autumn Challenge thread, probably as a Thanksgiving card. I'll look my basic template out and put it on the Template corner. I never buy cards any more, I just make an individual one and everyone gets their own personalised greeting. By using a standard stationery size I can also use a standard envelope, in this case I use an English C6 (you may know this as a quarter fold envelope) so I always have an envelope for any cards I print.
