I made frames for all four singing Xmas trees last year. I take photos of my project in case others would like know how build my my projects. I made my own leaping arches and modified the RGB pixel kit so it was easy to setup on any surface. If you want to know more about the framing for the trees let me know. You can keep it simple. Mine are very flexible. Can hang on home, sit on solid surface, or on grass. Depends on what you want to spend. The basic frame is very light weight. If interested it would be better to talk over the phone.
