After a shaky start, then re-cutting, I am at this point:
Yes, that is a large star laying on my floor! Correction: laying FLAT on my floor!
This star has a tendency to "lump" in the center, with the angles and bias that is no surprise. Once I got the setting triangles and squares on, I put it on the floor and got the iron. And I steamed it into submission! It is still laying on the floor so it can dry thoroughly with no distortion.
