String quilts were rarely published so the variations
don't have "real names" or "book names". This pattern, most often seen
in southeastern Pennsylvania, is a mystery design.
It's far more organized than the usual string
quilt pieced of random or regular strings of fabric.
Rickrack Antique quilts calls their example Chinese Lanterns.
Here's one that looks more like a lantern than many.
A variation that's more crazy than organized strings.
From the Pat L. Nickols collection

pieced blocks, nine patches, stars, etc.
A cousin to this example at the International
Quilt Study Center and Museum

I've never seen these variations on the string quilt published---
at least before 1970
From Julie Silber's inventory
You could see the design growing out of a basic melon or orange
peel with string piecing added.
Here are two melon variations from silks and mixed fabrics
But the extra curves....
