I've had several suggestions about how to print and use the hardness chart. I've checked printing costs and think I can do a custom design that is prettied up and will fit an approx 24" x 33" vinyl poster for about $30.
If you are interested see the general page and respond to the poll. If there is enough interest I'll go to the effort and post an update on final cost.
