What do you call these two stars?
I was checking Barbara Brackman's Encyclopedia of Pieced Quilt Patterns - and not having much success -
I was introduced to the bottom one as "LeMoyne Star" - it is a bit cumbersome referring it to as "a star made of eight rhomboids with 45-135-45-135 degree angles.
It is also a bit cumbersome referring to the top one as "an eight-pointed star made of parallelograms with 45-135-45-135 angles drawn on a 4x4 grid"
They are similar - but definitely not identical.
