Food / Large oval shaped Pierogies [7]

My grandmother used to make pierogies that were wonderful (as did everyone's Polish grandmother I'm sure). Hers were large and oval shaped with no pinched corners. I've never seen pierogies shaped like hers and can't get mine to look like hers did. Anyone know if pierogies like this were just her own touch or if these shapes were of a regional origin? (She was from Tarnov).
