Here is the result- I added a pocket cut on the bias to relieve the large filed of checks. I used a shirting bought from Michael's Fabrics. What a joy to sew fine shirting! The buttons came from Atlanta Thread and Supply- I bought 144 buttons for something like $1.49. (just kidding, but they were really inexpensive and I've used them on several shirts now.)
I LOVE the fit on this shirt! I made a mistake on the front placket though- I applied fusible interfacing (why??? I never do that!! I was on auto-pilot, I guess) and it is stiffer than I like. I also spaced the buttons 4" apart (again, why??? I usually do 3.5"- more space cadet sewing, I guess)
But really, it is fine and I love this fabric and I love this shirt and it was worth waiting for!
