Step 12: First steps 2 - timescale
Obviously if you fit the quilt before the roof goes on it's easier. But I didn't plan to reroof the house just yet awhile.
It is a two-person job. I fitted a lot of quilt on my own, but I didn't enjoy it, and I made a poor job compared to when I had a mate.
Also, some of the work is uncomfortable and unpleasant (eg squeezing into the eaves): it's nice to share it with a friend. Even better with an enemy...
