So they all have the top levels added now as you can see.
They are around 14” to the top of the merlons.
I have then cut out from cereal boxes, all of the merlons that I need.
I have been flying through the stage where the Merlons are constructed thankfully. Around 40 left to assemble (which I plan to do tomorrow night).
I have also received my Styrofoam and am just waiting for the wire cutter so I can get the broken sections started properly (not just the shell of them as seen above).
