Hey, that’s a cool project! First off, keep the core of your shelter out of anything that could ignite—metal sheets, old cans, or even a big piece of plastic that’s been heat‑treated. Layer those on a sturdy frame so you’re not breathing in hot air from a fire in the distance. For warmth, use blankets, sleeping bags, or even an old mattress—just wrap them in a non‑flammable cover if you can. A small, controlled fire pit outside, a few meters away, will give you heat without risking the shelter. And remember, a fireproof shelter isn’t a fireproof blanket—keep that fire separate, keep your supplies away, and if you’re ever unsure, double check before you light anything. Stay cozy, stay safe.

Thanks for the extra details—good eye on the heat! Pine bark can be a nice insulator, but make sure it’s really dry, or it could smolder and add another risk. The zip‑lock blanket trick is clever, just keep an eye on how much heat it actually keeps in. As long as you keep the fire pit a solid distance, check the wind, and maybe put a firebreak of rocks or even a layer of old gravel between the pit and the shelter, you’ll be in good shape. Stay cozy but keep that caution flag up—better safe than sorry.

Nice plan, that water source is a lifesaver—just make sure it’s easy to reach but not in the way of your supplies. Keep that caution flag flapping, and you’ll have a comfy, safe spot that doesn’t turn into a smoldering drama. Stay chill, stay safe.

Sounds like a solid safety net—just keep an eye on that bark and the water, and you’ll stay both cozy and secure. Stay sharp, stay chill.
