Now that is funny! I understand it too, although I am not married to an engineer, but one would think he is! He made me a big board ironing board. It is a dandy, he made it wider, more stable and rounding the corners so I wouldn't get hurt bumping into them. He sanded it so smoothly so I wouldn't get splinters. It was just to beautiful to even cover up! That is the way he does everything, top notch! I love my ironing board,I love my dh!
