It seems everybody is using PVC pipes to mount pixels to outline doors, windows, etc. I don't quite understand why because those PVC pipes are bulky to store, heavy, require drilling into brittle stucco, etc. Why aren't people just using the "PixelTrimSystem" from holidaycoro? It's not too expensive at $4 for 2.4m (though it adds up...) and you can use zip ties on mounting positions every 1m or so. I must be missing something.
