For years the owner of this quilt and I have puzzled over the pattern.
She's drawn it up. She is going to make it, she says.
I am not.
But it does stick in my memory because it is so odd (and so difficult to draft---much less sew.)
I was looking at the pictures of cheddar quilts that Kathy Sullivan has collected and came across a cousin.
It's similar in its kind of yin-yang design but this doesn't repeat in the same complex way. (See below for the true Yin-Yang symbol.)
Neither are in my BlockBase computer program or Encyclopedia of Pieced Quilt Patterns.
This is the closest I can find---but it's a distant cousin. Carrie Hall called it Spinning Ball.
The date on the red and white quilt is probably 1930-1950. That curvy ice-cream cone border makes me think it's after 1930 and so much Turkey red would not be likely after 1950.
The chrome orange block quilt is probably early 20th century, or possibly late 19th when so many Southerners made graphic designs with solid-colored cottons.
Thanks to Barbara and Kathy for the pictures.
