I can honestly say that I teach full time and have totally fell in love with the Crafter's Companion Alcohol marker paper. I have also used Copic X-press cardstock and Neenah, Gina K has a great paper also. I have found that you don't want to continue to change brands of paper because they all work differently with alcohol ink so if you keep changing paper, you will always have to "relearn" how the ink and paper work together (inconsistent results).
