storing bear hang string

Wind it around one of your water bottles or cooking pots. A bit of duct tape, gorilla tape or leuko tape will keep the two ends in place. Water bottles also make great places to store 4 to 10 inches of such tape, ready for use.

This is the best way I know to coil thin line.

Here is the abbreviated version of paracord management.

Same technique, just explained a little quicker.

What kind of string/cord are you using? If it's braided line, the technique used by rock climbers for their climbing ropes may be worth a try. They just stuff it into a stuff sack randomly, then feed it out carefully when removing from the stuff sack. When I started climbing I couldn't believe it would work, but it did, every time without fail. Never knots up, and doesn't put twists in the line. Don't know if it will work with thin braided line, but don't see why "knot." Worth a try.

Wrap it around an old credit card.

I'm using 2.2 mm zline slick.Seems to test my patience a lot as I prepare to throw the line .Just looking for a way to make this part of the day easier.

Shoving into a rock sack works fairly well.

When you wrap around anything, you put twist into the cord which then leads to tangling unless it is unwrapped in reverse.

When coiling a rope properly, when you make a loop by bringing hands together, you actually roll the rope between the thumb and index finger so it un-twists and relaxes it, then it lays flat. Same principle applies.

I didnt have much issue with 2mm
The smaller stuff I use now IS worse.

With any piece of rope, if you simply take the two loose ends and tie an overhand knot it will rarely get tangled up.

If you have something in a stuff sack – sleeping bag, etc, just wrap the cord around that. It will serve as a compression stuff sack that way, getting a little smaller (or a lot if you want to apply tension on each wrap. The larger diameter means it won't take as many wraps as a water bottle to store.

Thanks everyone for your suggestions.I'll be trying them all out soon.

I use the little plastic piece that kite string comes wrapped around.

Following the logic of a climbers' rope bag, I made a stuff sack with a 3/4" opening that I stuff my line into. I can tie a rock on the end of the line and toss it over a branch and the line will pay out as much as needed never getting tangled. The bad is I made it out of camo patterned material so I nearly lose it every trip and it is tedious to stuff the line back in when packing up.
