I've only seen pictures of three of these quilts, and I find them fascinating, as it's a pattern rarely seen, so when Common Threads Quilting announced they were starting a BOM for it, I couldn't sign up fast enough. I got my first shipment today.
I was ready to do another broderie block for my Morrell, but I may have to squeeze this in first. I'm still trying to keep current with a BOM past the second month, but it may be a lifelong quest for me! The good part about Common Threads is they post a picture of the current month's block to use for reference. Here's the first block.
Here is another version pictured in the book Glorious American Quilts by Warren and Eisenstat.
And a third version, which was formerly in the inventory of Legacy Quilts.
