See more about Pickle Dish on my June 14th post.
And click here at the Quilt Index to see a great Pickle Dish in the collection of the North Carolina Museum of History.
The quilt in the unknown pattern looks to be about 1880-1920 by the way the greens are fading from the light. Those fugitive green dyes tend to be after 1880. In the lower right hand corner some one has patched an area with a piece of 1930's Nile green. The chrome orange (what we call cheddar) is also fading and splotched, color loss often caused by washing.
The pattern doesn't appear in my Encyclopedia of Pieced Quilt Patterns. For years I figured the quilt was a one-of-a-kind design but recently I found two more in online auctions.
This one looks to have been chrome orange and fugitive green too, although arranged in the opposite fashion. The dyes are really faded here, probably a combination of hard washing and too much sunshine.
Again this one looks to be 1880-1920 by the dyes.
Here's a later version---by the mixture of bright colors with white I'd guess after 1930.
And I noticed one in the collection of the International Quilt Study Center and Museum. Click here to see it:
They call it Sunrise.
So what's the deal on this clamshell with triangles?
Is it a pattern published in a source obscure enough we pattern collectors haven't yet come across it?
Or is it a regional pattern passed from hand to hand and never published?
I'd bet it's Southern. Quilt historians working with regional Southern patterns like Rocky Mountain, Whig's Defeat and Pine Burr have noted the prevalence of arcs and strips pieced of spiky triangles and diamonds in post-Civil-War Southern quilts.
Whig's Defeat, about 1880-1920.
There have to be more clamshell quilts out there.
