Another thing to consider is making the edges round instead of pointy. I have dresdens done both ways. That way you would probably have enough fabric to turn under, and you would not need to use stabilizer, etc. Just make a small plastic pattern so they all match. If you use that certain plastic, you could iron the edges under, ready to applique. I don't know the name of that heat resistant plastic but it is good. Then you could applique using any of the mentioned methods. Best of luck in doing whatever you decide.
