This model of the George and Tula Christopher Center  was unveiled at the churches dinner dance.  In addition to drawings and renderings (colored drawings) on easels, the architectural model was looked at the most for the complete picture and understanding.  I still remember how much work it was to cut out the trusses. Those trusses were cut out of 4-ply 1/16″ white museum board and were cut out with an exact -o knife. Taking my time to scribe a line, then another and other before going through the board.  Took a long time to do but, was well worth the effort and effect.  The church center still has the model and on occasion when I do see it, it still looks like the day I made it.
