A near reverie of admiring introduction for this block was published in November, 1935, by Nancy Cabot (scroll down to tile):
"DIAMOND NET is one of the most interesting quilts to observe. A single block creates the outline of one design, while an entire quilt composed of DIAMOND NET gives the observer more than a half dozen designs formed by the colors used. There are several pastel shades and one dark shade as an accent. [... Here] one block scarcely does an entire coverlet justice."

Note also, if you have access to a local library, Cabot's articles in the Chicago Tribune are online, via ProQuest's Historical Newspapers. More than 1300 of her designs and a sampling of her insights are also available in Jinny Beyer's, QUILTER'S ALBUM OF PATCHWORK PATTERNS (this one is #430-4). Learn more (at Illinois Quilt History) about Nancy Cabot (Loretta Leitner Rising) and her long career in various jobs at the newspaper.
Compare with HOMESPUN BLOCK, another design shaped primarily by its outline. Rotated 90°, DIAMOND NET is also reminiscent of a traditional Japanese patchwork named PINE BARK DIAMOND (Yosegi Matsukawabishi), illustrated in JAPANESE QUILT BLOCKS (#61), by Susan Briscoe. See a listing of recommended Quilt Design Books.
For the diamonds, compare with OLD FASHIONED PIECED BLOCK and RAIL FENCE. On the "net" theme, see COBWEBS.
