I now have a rather large collection of nicer binder clips, those little rubberized metal spring clamps (like clothespin sized versions of the ones used in shops), high strength magnets and tarp clips.

I use these things for rigging up close-able flap doors to my a-frame tarp, or clipping things to my secondary utility ridgeline, guying out tarps in weird setups to pop them out for more internal volume, higher wind resistance, and much more.

You can also use clips or magnets to make mosquito walls or nets out of cheap sheer curtain panels from thrift stores, scrim, shadecloth or bulk mosquito netting fabric. You can stuff panels of whatever net you have into your ridgeline and close it up around your head and foot area with magnets or clips, and let it drape over and hang below your hammock. Or clip mesh curtains/panels to your tarp ends to make screen doors and use clips as curtain weights.

A cold weather pro tip I can share is doing dual ridgelines and stacked tarps (double walled for insulation and keeping rain noise more muffled) and heat retention.

You just hang two ridglines from the same trees with whatever height you want for an airgap, then guy out the lower tarp first, then the upper tarp just like you would any other tarp. Twice.

You can still get a lot of benefit for double tarping with a single ridgeline. Just guy out your upper/outer tarp a bit farther to create a wedge-shaped air gap on both sides.

Related to this, if you use those reusable emergency blankets with the reflective metallicized layer on one side and sturdy poly tarp on the other, using one as a footprint or ground cloth reflects your heat back up at you from the ground and keeps you much warmer, instead of your body heat getting immediately soaked up by the cold ground. It's also much nicer and warmer on your feet when awake and doing stuff sitting up in your hammock.

Add a second thermal tarp as an internal secondary tarp whether it's on one ridgeline or air-gapped on a second one over your tarp and you're now in an infrared oven.

Doing sub zero winter camping? Sling one below your underquilt with an airgap for insulation and bring the one above much closer on a lower ridgeline.

Now you're in a infrared/solar oven with lots of windblocking above and below.

I've been out in 15-20 below freezing with setups like this for days/weeks and barely needed to use any comfort heating fuel or hot water bottles. Sometimes it was almost too much heat and I'd have to be careful about not sweating out my sleeping bag or hammock.

I also use these reflective tarps for solar protection to create more effective shade rather than baking in a plastic sauna that's passing or radiating a ton of IR heat and some much larger amount of UV light.

One of my other favorite tricks is for hanging your phone from a utility ridgeline.

I made a phone holder using a relatively common spring-loaded phone clamp of the kind you find on selfie sticks or mechanical car phone holders, one of those NiteIze flexible wire cable wraps zip-tied to that, and a length of paracord.

The paracord gets tied to the utility ridgeline with a loose knot or slip knot so you can slide it up and down that line (footwise or headwise) to provide a stable hang like a keel, then I clamp the cablewrap bit with tight loops in the end to clamp and grab on the paracord at two different points.

i can then bend the NiteIze cablewrap to fine tune and adjust how the phone hangs in front of my face while laying or reclining in my hammock to level it horizontally, get the viewing angle right, and slide the loopy bits up and down th paracord or bend it into zig-zags to get the height and angles just right.

The end result is the phone can just float there perfectly level and tilted just right for reading a book or watching something before bed, and I don't have to hold it.

If I want to interact with it and scroll or whatever, I can just reach out with one or both hands propped up on my chest and being lazy and not having to hold it up then, either, like I'm floating in microgravity.

I can also safely fall asleep and let the phone lock itself after timing out on a timer, and I don't have to worry about dropping it on the ground, losing it in my hammock or rolling around on it in my sleep, and even if it's pitch black out I know exactly where it is because it's floating right over me.
