Our second floor hallway is irregularly shaped (with a couple jogs at top of stairs), and we just added a new entrance to the master BR that extends the hall but with a doorway (far left of image). We are struggling with what to do about area rugs and runners.

Right now, we have a wool oriental runner on the stairs. We had a 3x5 (approx) area rug at top of stairs, then a long runner for the main hall. We now have the 42 in x 72 in entrance to MBR to cover too. All are hardwood floors. (There is a raised saddle at the master doorway, so can't continue a runner through the door threshold.)

It seems like we still need 4 rugs (stair runner, top landing, main hall, MBR entrance). Wondering if anyone has ideas or guidelines for mixing different rug designs. We don't want to do same pattern everywhere, but getting 4 different patterns to work together may also be tricky. Don't want a hodgepodge!

Any thoughts to guide us?
