You know what? They have a picture of this block on the website but all their information and directions are for a different "prairie queen block". I don't think we have found the correct name for this particular block yet. Keep searching, please. :)

There are some blocks that have many names.

There are some block names that have several designs.

It can be confusing.

I redrew it on a 14 x 14 grid - now it looks more like the original post.

And on a 16 x 16 grid.

Yep, I found it in block base and it's Prairie Queen and I didn't see any other name for it, there is also another block by that name that doesn't look anything like it.

Interesting. I will be checking back to see if anyone has come up with a name. So many times, our pioneer folks moved on, had patterns they assigned a new name for or adapted them a bit. A quilt museum might be the place to ask for name of that block.
