I tried wearing the coat last night, and was actually very pleased with it. It's warm, and the extra material in the skirts from the two side-triangles means that when I sit down in the coat it does not gape. It just spreads out and continues to cover my knees like a champ.

Pardon DH's messy office behind me. Also I have no idea what that white stripe on the coat is. It wasn't there when I looked down at it. Some artifact of the camera, I think.
I have a nice kilt pin somewhere, which I'll use to close it instead of the morris dancing badge featured here. I'm in two minds about whether to line it with a lining fabric or just put tape over the raw edges, but the material doesn't fray anyway, so I don't necessarily need to do anything.
Also, keep your fingers crossed, but Son is currently getting insurance for fast food delivery, and once that goes through, he may actually have a source of income! Which would be both of my major hopes for this year achieved. (A source of income and a place to live.) It's not a great job, but it's better than nothing.
