I've done an initial search and haven't found any place that has Crane's Cover Stock or Platinotype in rolls. Does any one know of a source or even if it is possible to get?

I am planning to do platinum prints from Cirkut negatives. 10 inches high by as long as 6 feet.

If I can't get Crane's, is there another paper that comes in rolls that will work?

Thanks in advance,
