Oh dear, another pattern without a BlockBase number.
It's a full-size quilt and I'd just leave it be as one individual's vision
but I see I have two examples.
From Pennsylvania eBay dealer GBBest.
Serious fading in the pale gray areas here has altered the pattern.
I bet those large diamonds that are so gray now were once blue or green...
and probably looked a lot more like this when it was newer.
Stella Rubin's shop
From Franklin County, Pennsylvania
And then I found a third....
It's obviously related to these end of the 19th century giant Pennsylvania stars like the one above that collector Phyllis Haders bought from Franklin County, Pennsylvania.
A few years ago I did a post on these whole-top designs often called Carpenter's Star (no BlockBase number there either.)http://encyclopediaquiltpatterns.blogspot.com/2017/05/mennonite-stars-whole-top-designs.html
If you are looking for a little Y-seam practice this might be the pattern for you. There's a pattern for a 72" star in the link above and all you'd have to add is a star for the squares around the central star---the squares finish in the pattern to 10-7/8".
Or maybe you'd rather piece it as a block as in this quilt from Julie Silber's
inventory. No BlockBase number on this one either.
Debby Cooney made a comment in that post about the design source for the large Carpenter's Star:
"Franklin County, Pa., antique dealer Morgan Anderson considers this pattern to be a signature design in that area. He has seen & sold many since the early 1970s. [One you showed] came from the Martin family, Old Order River Brethren members for whom this star was a favorite; they made several. He sold Phyllis Haders the one shown here. "
