Don't know about the name but it is quite interesting.

Looks like a " self-designed" by originator to me......She did a good job, whoever she was......

Have you checked out Quilterscache? They have hundreds of quilt blocks and you may find it there.

It is an intriguing block. I will be interested to see what answers you get. These ladies are so smart! Soon you will have the name and how to put it together. I'll be so curious about the answers.

What a great, complicated, seemingly old-fashioned block. It appears to me to be a variation on the Weathervane block, an example of which can be viewed here http://www.generations-quilt-pattern...ilt-block.html and in BlockBase.

Imagine the Weathervane block as the center of a larger block, turned on point with the HSTs in the Weathervane illustration eliminated to form a five-square criss-crossed X. Add isoceles triangles to the 4 outer squares of the X, draw connecting lines from point to point of the isoceles triangles to create the square, and "fill in" with diamonds and triangles. It should be fairly straightforward to reconstruct the pattern (and crazy-making to sew!), but I can't find a name for it. I checked Blockbase and didn't recognize it. Good luck; I would love to know the name.

Could it be a variation of a North Carolina Star?

I drew it on a 12 x 12 grid.

I found the pattern in Barbara Brackman's Encyclopedia of pieced patterns. On page 367, her number 3047. Prairie Queen from Household Magazine 3/1937 OCS/Wheeler (Old Chelsea Needlecraft Service).

Thanks! With a name, the pattern is very Googleable.

Whoever made this did a great job on her seams. So many old quilts I have seen the seems vary so much to size where if washed it seems like they would ravel out, hers look like full 1/4 inch with no variation, Kudo's to this person!
