This model is simple to make and the result is beautiful! It is made up of twelve units We will start by making two or three units together in the first hour. Then I will demonstrate how to put the units together to make the finished model. This will probably take about half an hour. You can use the remaining half hour to continue making units and assembling the finished piece.
