Nice leisurely morning sitting with my wife, reading and drinking coffee. Then figured I should probably do something useful, so got some more fiberglass fitted, got the back box that will eventually hold a fan fitted (what I had previously was a botch with a regular back box crudely held in place so I had enough light to work). I've gone through more of the narrow fiberglass than I thought, and it turns out that having bought a full pack of wider fiberglass I only actually needed three pieces of it out of 11. So I'm not sure whether to look to sell the rest, or cut it to lengths and lay it perpendicular to the joists. Suffice to say I have plenty of fiberglass to work with right now....
