Start with several of the PF frames in the center and let the bees have them to establish housekeeping on and start regressing to a more natural size. I assume that is part of the reason yoy are going foundationless. When the bees have capped brood on two frames, put your first foundationless frame between the PF's and slide them tight to gether. After that floundationless frame is drawn, full of brood, and capped: Put another one beside it. In better than a month, When the bees are working on the outside two frames, move them to the center so you have drawn frames in 1 and 8 and move a frame with brood up into the second medium and put it on top or under super, something to be said for both. Keep feeding in the foundationless frames to get them filled. Put a bunch in at a time and you will have some straightening to do. Send those nasty drawn PF's to me after you have replaced them with foundationless and I promise I will properly dispose of them in an effiecent manner.
