Polyester String Quilt
I don't know if a pattern has ever been published for this whole top design
of string-pieced diamonds. But it's a pattern you often come across.
It's one of the new numbers in the third edition of the Encyclopedia of Pieced Quilt Patterns.
I sent the drafters this sketch.
Source: Common String Quilt
In this edition I added many designs that are common
but do not (yet) have a published source.
Here's their fix from the page proofs.
Amelia Etta Atkins (1879-1965)
from the Tennessee project & the Quilt Index
Most of these are from online auctions.
Bertha Virginia Riddick from
the Michigan project & the Quilt Index.
Does it have a name?
Variation, not indexed.
