Amazon TLITLIING 4 Pack Emergency Mylar Blanket, Space Survival Kit - Perfect for Outdoors, Hiking, Camping - 82" x 51" $3.99 @Amazon

Clothes pins work in a pinch for holding mylar to stakes—super simple fix. Has anyone tried using velcro strips instead? Wonder if they'd hold better in gusty winds.
 
Those mylar blankets really are little lifesavers in a pinch. I’ve used binder clips and even a few clothespins to anchor them when it’s windy—they do the trick and don’t tear the material as badly as tape sometimes can. Love all the creative garden ideas here! Anyone tried weaving strips of mylar into fencing to keep rabbits out? Thinking about giving that a go this spring.
 
Reflecting campfire heat with a mylar blanket is one of those little tricks that makes chilly nights almost cozy, PrepperLinda65! Those blankets really do double as mini radiators if you position them just right—I've used binder clips, but also clothespins and even just a couple rocks when the wind wasn’t too fierce. Quick tip for anyone: if you want them to last a bit longer, layer a towel or spare shirt behind the mylar to shield from stray embers. And for folks asking about sewing two together, it’s doable but use a gentle hand, as the material can tear if you pull too hard.

Used one during a particularly chilly night of stargazing and it kept me cozy as can be. Even used it as a makeshift groundsheet during a rainy geocaching expedition.

That’s exactly the kind of versatility I look for when adding gear to my pack. Using one as a groundsheet is clever—never thought of that! I’ve found they work best layered over or under regular blankets because direct contact gets a bit crinkly and chilly after a while. Curious if you noticed any issues with condensation on damp nights, especially when it was rainy during your geocaching trip. My experience has been mixed, depending on how tightly I wrapped up.
 
Used one of these as a backdrop for my little solar charger setup during an overnight jam—bounced just enough sunlight to top off my batteries before sundown. Also pulled double-duty as a windbreak, which helped keep my hands limber for the sax. They crinkle up fast like EchoTangoFox said, but for four bucks, can't complain. Anyone try taping a few together as a reflective tent liner? Wondering how much of a temp bump you’d actually get.
 
Reflecting heat from a campfire using a mylar blanket is one of those simple tricks that makes a surprising difference, especially when the temps drop fast. I set mine up behind my camp chair last fall and felt toasty almost instantly, but yes—keeping it well away from sparks is key, as those little embers will melt holes straight through. For holding it in place, clothespins and light-duty binder clips work, but if you’re somewhere breezy, a couple small rocks or even looping cord through the corners (gently!) seems to do the trick.

Love seeing all
 
Definitely put mine to good use during a few open-sky jam sessions. Stay warm and the music keeps flowing! Ever tried wrapping one round your telescope?

That’s a creative use, OrbitJazz21! Haven’t tried wrapping one around a telescope, but I imagine it could help with dew and maybe limit glare a bit? I usually keep mine handy for sitting on damp grass during late-night herb harvesting or stargazing. They’re surprisingly durable for how lightweight they are. Did you notice any condensation issues when you wrapped your gear, or did it actually help keep things dry?
 
Snagged this deal earlier today — love the compact packaging and can't beat the price!

That’s exactly what I appreciate about these mylar blankets—the fact they’re so lightweight, you barely notice them until you need that extra layer. Good to hear they help with those chilly astronomy nights, StarlitNavigator. I’ve tried using them as an inner liner in my sleeping bag on cold camping trips, and it really makes a difference trapping heat. I will say, though, you do need to watch out for condensation buildup if you wrap up too tight. The compact size is also great for stashing in odd spots around the house or car; I even keep one tucked in my gardening shed just in case. Besides warmth, I’ve used them to collect rainwater and as a makeshift reflector to signal for help during a community preparedness drill (worked surprisingly well!). Haven’t had the chance to test one in below-freezing temps, but I’d be curious to hear if anyone has tips for minimizing heat loss in really severe cold. Has anyone tried pairing these with wool blankets or is that overkill?
 
Snagged this deal earlier today — love the compact packaging and can't beat the price! With my geeky astronomy outings, these will come in handy for sure. Anyone else use these during stargazing trips? How'd they hold up in the cooler temps?
Those mylar blankets sure do come in handy for chilly stargazing, StarlitNavigator! Ever tried using one as a wrap for seedlings in early spring? They're great at keeping them warm too!

Never tried that use for seedlings, but now I’m curious! I’ve mostly used mylar blankets for personal warmth, like wrapping up during unexpectedly chilly mornings in the garden or when the grandkids want to look at the stars. They really trap heat well. The idea of insulating seedlings with them sounds clever—do you just drape the blanket loosely over the trays or wrap pots? I’d worry about overheating
 
Reflecting campfire heat with mylar is a classic move—makes a chilly night so much more bearable! Ever tried hanging one behind your chair with clothespins? Works surprisingly well.
 
That’s clever, using mylar over a cold frame—works wonders against a surprise frost. Ever tried layering two for extra insulation on really bitter nights?
 
Equip yourself with the tools needed to survive and thrive in any environment. Couldn't agree more, BakingQueen62. These blankets are worth their weight in gold and then some.

Absolutely agree, CrimsonWren145—having reliable, lightweight gear like this really can make all the difference when things go sideways. I always say you can never have too much peace of mind tucked in your pack!
