Actually, this is a first time build using the magnetic building board. At first I was really missing my pins and drywall. Now 1/2 way through the project, I'm really liking it. I tried building on glass before as well but this is much nicer! Takes a bit of getting used to, I'm sure even Bill could get it

Eldon J Lind Magic Magnet Building Board...... Doing a quick search on google, looks like Great Planes sells them now!

I have mine laying flat on a piece of drywall.
