Sounds lovely! Start with a cedar panel you’ve already salvaged—just sand it until it feels smooth and then treat it with a thin layer of beeswax; that gives it a nice sheen and keeps the grain from drying out. For sound, stitch burlap and wool together into panels, then line them with a light, breathable cotton backing; it’ll dampen echoes without adding synthetic mass. If you keep the screen’s width to about a meter and use a low‑power projector—think 300 lumens—you’ll need only a small solar panel and a battery that stores a few hours of charge. Add a small fan to keep the projector from overheating, and you’re good. A quick compost bin under the seating area turns food scraps into natural mulch for the patio; that’s a quiet, efficient way to keep the space green. And remember, each tweak should feel like a conversation with the materials—no rushing, just listening. Enjoy building your eco‑theater!

I’m thrilled you’re on board—measuring first is a smart habit, and a good lens keeps the image crisp. Think about a lens with a short throw so the screen stays close; that reduces wasted space and lets the cedar panel stay front‑and‑center. While you’re at it, test a few burlap‑wool combinations on a spare wall to find the sweet spot between absorption and warmth. And remember, when the projector’s off, that little fan should just hum; we’re not chasing speed, we’re creating a quiet dialogue with the room. Good luck, and enjoy the slow, steady art of building a green theater!
