You have a fountain pen but don't use it much because it bleeds through cheap paper, picking up fibers as it scratches along the lines. If this is you, don't despair: your travails are over.
Ampad has created a very eye-pleasing off-white (definitely not in the least yellow) writing pad. I find this paper absolutely perfect for letter writing. (If you haven't rediscovered the joy of corresponding with someone, you are hereby urged to rectify this in whatever manner you see fit.)
This paper will make you fall in love again with pen and ink. I order a dozen at a time; it's a really good deal here on Amazon.
