I just finished a Victory Quilts quilt from Elenor Burns and your garage sale find looks like the Fallah block in her quilt.
Pretty amazing to me that you would have someone making that quilt and selling it so quickly!
********* I am repeating someone, I see ... I didn't read all the postings, so I will stop right now, and say ... sorry for repeating what Miss Butterflywing said ... she did a lot of research to help you. Your purchase was quite a gift <g> cool!
