Step seven: The morning after

IF you knew earlier how MUCH to angle each succesive row the top of your structure would come out more like a dome rather than this sort of wigwamish/hogan shape.
Still...even with that bit of trouble the top of the strucutre is enclosed and it can be boolean carved on the outside to round off the edges.
I chose not to because even at 6'2" I was stretched as tall as I could get to get the last few primatives to the top.
