I recently tried my hand at scratch building some table top terrain. The subject I chose was a "marabout" These structures (qubbah in Arabic) dot the landscape of North Africa and are actually tombs of local holy men (or saints). The following pictures show the final results. This could be a good addition for any desert table. The link is to a walk-through on how I completed the project.
