I know I’ve said this before, but it bears repeating. Find a local
printer to work with. They give better service, you don’t have to pay
shipping, and you can request the paper you want.
We have a local printer who is doing amazing things right now. Her
and her husband see a lot of people asking for heavier card stock
with a semi-gloss on the front. People love it, but there are several
types of gloss on the front that you would be looking at in person to
see how they look and feel, how other cards made similarly look and
feel. It puts you in a position to make a knowledgeable decision.
