It's something that has been discussed, but at the moment unavailable. I guess if there was enough demand it's something we could look into. The truth is that getting an even and consistent coating of eggwhite on paper rolls is a lot trickier than it sounds. I can talk to Dick about it because we might be re-tooling some equipment this winter (too busy with APIS and other events rights now) and I don't see why not. Well, except getting rolls that size is becoming more difficult.
As for the 48", I suppose you could call up and talk to Dick or Melody and find out if they'd do a special cut. I believe the width is 48" so if you're looking for 60x48" for example, I believe it would be doable.
