The biggest challenge was working around cracks, missing knots and other blemishes on the white pine boards. Saying they were "rough" is an understatement, but we managed to find enough good boards, or at least good sections of boards, for the most-seen areas and to hide less-desirable pieces where the closet, cabinets and bed will go. What little wood was left over will make great fuel for the grill.
Now that the floors are in place, we can't put off figuring out the plumbing any longer. Or...maybe we'll do that after we trim out the windows and doors?
