|Decided to go with all 3-oz cans for the spine, topped off with a toilet paper core|
The cardboard discs, should in theory, be able to define the spinal ridges. I decided to simply place a large can at the bottom to take the weight of the structure, instead of trying a get a stake-in-the-ground type anchor mechanism. Whether this will be enough to support the weight of the head and also not fly off in the wind, only time will tell!!
