old quilt
I believe your quilt to be pre-WW11. The swastika had the arms turned one direction and the Iron Cross had the arms turned the other way. No, I do not know which way for which one.
The "Grandmother's Fan" quilting pattern was used forever with hand quilting. Just a pencil or piece of chalk with a string tied to it, then knotted at intervals to make the fan spaces. Hold a knot tight against the quilt top, draw a 1/4 circle, then move to the next knot, etc. til you have the fan, quilt, do some more. My Mother used this a lot for "everyday" quilts.
