I don't know if you're talking one piece of a PP or multiple smaller sections into large ones.
It doesn't matter (aside from printing considerations, but foundations can always be joined).
What ultimately determines the size of a particular PP foundation is the nature of the shapes, and how many pieces you can sew contiguously without running into the PP wall, where you can't sew the next piece on completely with a straight seam - it jigs or jags or something.
I've made a Kaleidoscope (a la Paula Naderstern) that was ~60" inches across, so each ray was 25" long, but made up of many smaller sections.
But that was only because the piecing of the intricate design required it .
If I could have done it on one foundation, I would have - even at that size.
eta: Actually, I wouldn't have. Even if it could have been done on one foundation, ther would have to be break somewhere, and I would have probably broken it down into two sections.
What would be the big deal about that one seam, especially as it would probably NOT require any matching of points?
