Update:
(Note join of 10 foot and 4 foot sections to make long axis; nearest example is by the tree)
Corner bracing:
Simple stakes made by cutting a plank into something you'd impale Dracula with. They went in really well on one side but only about an inch or two on the other, the ground is already freezing up on this side I guess. No matter, I think these were unnecessary but since my long dimension is weak due to the join I thought I'd slap a couple in for extra peace of mind.
Lumpiness:
My backyard is a bit lumpy so there are some stretches with gaps of 1-1.5 inches off the ground. I'm going to be using a liner so somewhat less concerned about this, and to help a bit I'm going to start packing snow into these areas to further help mortar them up a bit.
