I spent most of the month working on the interior wall assembly of this tiny house at Hammerstone. An earlier class taught in it had finished with the first layer of rockwool insulation, and the following class on trim carpentry was in two weeks. First came the shiplap ceiling, then the second layer of rockwool set in horizontal furring strips for a thermal break. Next came drywall sheets, primed and painted with a tear-away bead. The final window casings were built in class.
