They don't stretch if you don't man handle them...even without starch, I swear. Only two edges are off grain and it's not truly bias since it's not a 45º angle cut. Once they're sewn back in to strips, there's no bias to worry about. Stabilizer or interfacing is going to unnecessarily add to the bulk of the seams where the six points meet.
