The pattern doesn't specifically call for any lining, much less bag lining. Others have done it though, and I love how it looks so I'm going to pile on the bag lining band wagon. I cut the strips and sewed them together (opted out of continuous strip bias as it takes me longer to do that). Then I gather stitched them, only stitching one 30 inch strip at a time. This way the gather lines don't break or tangle. Then I start gathering (and gathering and gathering).
I was far too excited to measure or stitch carefully. I know my seam lines are not straight. But they're mostly straight and I can fudge a little with a hot iron. Once I make the two welts with the red, I'll have a pocket bag with red on the shell side and polka dots on the lining side. See how cute?
Once I got all the trim on I hand tacked it to the trim seam allowance. That way my trim won't have a tendency to roll out or sag, This pattern seems simple, but bias trim sewn to a bias cut edge is tricky work, I had to fight the tendency of the edges to stretch while I pinned and sewed. Even with stay stitching.
Here is the final garment (ignore the white string hanging off my elbow! I was working on a different muslin while we took these pictures) And a celebratory glass of wine!
