Happy Mother's Day, mothers.
Elaine Krajenke Ellison is a mother. She is also a retired high school math teacher in Indiana, and a quilter. She makes mathematical quilts, many of which are in private collections, but some can be seen publicly at places like the London Science Museum. Here's a small sample....
She also sells note cards with pictures of the quilts and an explanation of their derivation. I bought a set for my retired school teacher Aunt. They're a surprise birthday present, so don't tell anyone.
