It looks beautiful!

I really appreciated all the suggestions I received. As suggested, I stay-stitched the edges (which were all bias) and had very little distortion. I hated cutting off all the points around the edge, but since there was no easy fix, I decided that it was a “design element.” I ended up replacing a few of the muslin squares that were scorched and the new muslin fabric blended beautifully.

That looks great. Nice job.
