A good deal of shop work can involve planning and designing jobs. If you have not done so, outfit your workshop with plenty of paper, drawing tools, tape and planning aids, plus a desk lamp and a comfortable stool. Such creature comforts will help increase your enjoyment of home and workshop projects.
