How are we going to insulate the space where the roof and wall insulation meet?
When in doubt, more wool.
We filled the floor circumference crack with wool, we stuffed wool (washed in borax) below the kitchen window and more wool around the crown wheel.
Since had a few (20+) wool stuffed pillows remaining from the wall wool quilting project it made sense to sausage them to fill the gap in,question. Looks pretty sweet eh?
