Thanks, SkoutSews, Efemera, and annieeg!
The fabric was an internet purchase and when it arrived, I was surprised by how great the color contrast was between the sides. I bought it originally for trousers, but when it came, I decided I wanted to do something to play with the contrast. I love the grey underside of the fabric for the yoke and how it contrasts with the sage green. I kept the inside/reverse just the grey. Thought I might more wear out of it that way.
I was working out problems on an RTW jumper that I had traced and made up once. Before that I hadn't done this particular applique technique with my machine using soluble thread. It seemed like a good pattern for this fabric.
Mulled a bit on how to make working pockets on both sides, and still flat fell the side seams to make the jumper reversible. Gave up on the pockets and am glad I did, because I think they would have been too much for the drape. The "reversible hem" was also a challenge, but I got a lot of good input from sewing friends on how to tackle it.
It was fun to try to figure out. Thanks again.
