AC jacket - 3 pieces to go (couching)

This morning I laid out all the pieces except for the two completely unfinished arm pieces (it's a two piece sleeve). Lots of couching!

That last side back piece is only about 25% done, if that.  But I'm still kind of excited about maybe starting to attach all the pieces together.  Still going back and forth on whether to do it completely by hand or to machine stitch and then hand top-stitch.
