Lines or Squares: Doane Paper

A lot of designers like graph paper. Others like lined paper. What if someone invented lined paper that could also be used as graph paper and vice versa? Doane Paper has created such a beast; the best of both worlds, rather. I'm not a big fan of lined paper but I find this paper oddly alluring. So flexible. So functional. I see the next great typefaces sketched out on this paper.
