Aside from regular safrus, I write on paper for various things including gittin, kesubos, and calligraphy. Nevertheless, I have still not found an ink and paper combination I like. I have experimented with all kinds of ink, including dio and many commercial inks, and many different kinds of paper, and I just can't seem to find the perfect combination to make nice, sharp, letters. Nothing seems comparable to parchment. With paper, too, I have tried many different kinds, and believe it or not, my favorite is plain copy paper! Anyway, I would appreciate any and all advice, and hearing about what combinations work for you and for what. I would especially like to hear from people who write gitten. Thank you!
