Ok lets go with doing them either 3x5 or 8.5 x 11 inch.
If you make at 3x5 300ppi anyone wishing to can upsize and add a background and print out to save at letter size.
if you do at letter size [Patty B feel free to do this] I will type the recipe up on a 3x5 card for the exchange.
That should work for all of us.
