This is the question that I run into all the time when I bid jobs.
Today I picked up materials for a small job and I mulled over this question as I stood staring at the cargo in my truck.
Three boards of cherry and one sheet of 1/4” mdf core cherry… $217.
Well, at least I got the job.
Peace, Love, & Woodworking
