I just went and checked to see what the swastika symbol looked like. Then I looked again at your quilt. For the life of me, I don't see it - but it's not my quilt.
However, I did notice that not all the blocks are placed the same way. Which I did not notice at first or second or third glance - but THAT would bother me!
From left to right - for lack of a better way of putting it - The top left unit of each block will be described as horizontal or vertical
H - horizontal; V - Vertical
H V V V
V V V V
H H H V
I don't know if that placement was intentional or unintentional -
You know what you (and your mother) can live with - and taking out and replacing can be done -
