I'll be showing you how I made a fitted net to carry a nalgene bottle or other jar/bottle/item.
using the lid loop on the canteen works, but I have had several break after a while, and then I am doomed to loose the lid.
The net gives you multiple attachment options and offers some protection against rubbing.
I based my design on the instructions found here: http://www.knifeforums.com/forums/showtopic.php?tid/771863/hl/tutorial/tp/1/
I used a different knot for the bottom, in hopes of keeping the canteen more stable, but its still pretty wobbly.
Step 1: Gather the Supplies
1 Nalgene bottle (mine is extra awesome because I found it on the ground in La Grange TX)
2 Pieces of Paracord - 4 Armspan* piece and a one Armspan* piece
Lighter to prevent fraying.
Knot book - optional but I always like to have it nearby when working with rope.
*My Armspan is about 6 feet, if yours is significantly larger or smaller add or remove armspans to compensate.
Step 2: Tie the Foundation Knot
to start the knot, lay the cord into a cross shape, making each arm and top about 3 feet.
if you have trouble tying the knot, just search for some guides online, there are a lot of them.
work any loose bits of cord through the knot and make it nice and tight.
after tightening the knot cut and seal the ends of the loops so now you have 8 strands coming from the knot.
Step 3: Start the Net
it will take some fidgeting and adjustment of the knots to get them all the same distance from the foundation knot, and placed on the jar correctly.
I put my knots on the side, it may add more stability to have the first set of knots on the bottom to help flatten the contact points the bottle rests on. if anyone tries it let me know how it works.
Step 4: Continue the Net
just alternate tying the closer strands to each other so you create an X pattern.
make sure all the holes you are creating are too small for the bottle to fall through.
The finished product will look much neater if you take the time to make all the knots even
my bottle had 5 rows, yours might vary.
when you are done with the second to last row move to the next step.
Step 5: Finish the Net.
after tying the last row pull the cinch cord tight and tie a square (reef) knot to keep it tight.
If you want to carry the bottle by the paracord, and you left enough slack, tie a fishermans knot into the ends of the rope so you can adjust them and wear the canteen on a sling.
you can also tie a loop and clip a carabiner into it to carry from a climbing harness.
There are lots of options to carry the bottle now.
