It is looking great and will be like getting a hug from Dad when they wrap up in their quilts. Can you use the button/button hole plackets as binding? If you cut them off the shirt with about 1/4 inch of the fabric still attached, you could sew the remaining 1/4 to the front or back of the quilt (depending on how you like to bind) and flip the placket over the edge to have a nice finished placket edge to hand stitch down. The cuffs you could use on the back to write your label on and hand stitch it on when the quilt is finished.
