Wanted to follow up with how I mounted my technicolor lights to outline my sidewalk.
I zip-tied each node to 1/2" PVC (with bell ends). With all of the nodes mounted I can still fold up each of the PVC sticks so it will only take 10' of space to store.
For the lawn I got 12" pieces of #3 rebar and used 4 pieces of rebar for each 10' section. I drove the rebar into the ground with ~3" sticking up. I then held up the PVC to rebar and made a mark with a sharpie. I drilled a hole on the underside of the PVC at each sharpie mark. With all the holes on the underside drilled, the PVC simply slips over the rebar and sits atop.
