Years ago I used a homasote surface with wax paper and pins and it worked fine. I switched to glass since all the top R/Cers said it was the best. I have now switched back to homasote covered with wax paper because I ruined too many pieces trying to pry the wood away from the ca'd glass. Yes, I tried putting down wax paper over the glass, but then the problem was keeping it in place over the plans. Call me old fashioned, but pinning parts to homasote is just easier for me.
