We made a trip to the lumber store and then began the construction of the wall.
To insure proper lighting during the project we constructed a light bar and attached some floods and spotlights. The bulbs are a mix of warm and cool (color temperature). Modern florescent bulbs are comfortable work under like older incandescent bulbs which can be hot.
We used the paper pattern which we made earlier to cut out a masonite panel (three panels, actually) which will provide a smooth surface and also permit the exact shape to be readily available under the stretched canvas.
