Eight months later I found this plastic bag
And about four hours after I unpacked the bag I had this!
I used some pearl snaps from the Snap Source instead of buttons and I overlapped the shoulder flaps the correct way this time.
Another finished object
(*I was going to call this "UFO to FO" but then had second thoughts.... One of my professors at university was strongly opposed to abbreviations that were not universally accepted or might have two or more meanings. Prof barked loudly at anyone who wrote, for instance, that the child had a "TOF" - was that Tetralogy of Fallot or Tracheoesophageal Fistula? So, remembering his sensible words I rewrote the title of this post and hope now there is no misunderstanding.)
