#1 Resource for card stock; love their info resource too
I've been using Red River paper products now for about 2 years. I have a fine art photography studio and business and with their papers I have saved money and gotten just the results I want for printing my cards. I love all the options of the sizes and paper and am particularly pleased with the square polar matte...quality works great every time. And really happy with all the info they provide...from feeding printer, to cleaning printer, to ICC and proper color mngt to DIY canvas printing and stretching. Really great resource.
