Thank you! I wish I had put some interfacing in it to make it a little more rigid, or used a thicker layer of batting, but it suits the purpose. Mum was very happy with it, so that’s what matters! The fabric came from her stash (she inherited several bags of fabric from a couple of people in the last few years- it’s fun to dig through them and see what there it!), and the outer fabric was a very soft cotton. It was made into something else (the fabric was hemmed on 2 sides), but I have no idea what it was. The inner fabric came from either a pillowcase or a curtain/valance.
@AIMR and @Magpie, I’ve never seen that particular technique before (even though I have made vests and bags in the past), but it made for a nice clean finish. The only tricky part was sewing in such a narrow opening. And, the Japanese knot bag is on my to-do list, so I’m glad I’ve practiced the technique already!
