Found this mystery on a FB group-pattern is by Georgia Goebel, and I don’t believe it has a name! She did this mystery in 2013, I believe, and reposted the clues recently, along with the finished quilt, so technically, not a mystery!
My 7 yr old grandson has been with me a lot this summer, and he is on the autism spectrum. He loves puzzles, so I let him put all of the pieces of this quilt puzzle together for me....he loved it and asked if he could have the quilt.....well, of course!
The fabrics are actually leftovers from the quilt I made for his Mom last year.
Waiting on backing to arrive, and hope to get this quilted and bound before he returns to school next week. No idea how to quilt it...yet...
