Here is a picture of the completed shams.
I sandwiched the tops with batting and muslin and did stitch-in-the-ditch quilting. Then I added a two-piece back from the same dark green as the backing on the quilt that closes with hook-and-loop tape and sewed on the binding. Today, I finished hand sewing the binding.
The shams ended up about 33″ x 23″ and I think I will have to either buy queen sized pillows to go in them or make some to fit. It feels great to be so close to the end of a project.
