Delia's working on both bridges and scenery. She's outlined the mountains in good old Dow Foam and will build them beyond her outline. Roy has been casting bridge arches and stone 'skins'. The bridge he's working on has a curve to it instead of going in a straight-away. To have the arch pieces follow the curve, he takes the as-yet uncured molds with the castings still inside and clamps the mold to the bridge frame. When the mold cures, the casting will pop right out and match the curve of the bridge. I'm off in my corner, meanwhile, building and painting Plasticville buildings to go on the lower track step (the one with the graphic background of trees and sky).
