Messenger bags are great but sometimes the long shoulder strap gets tangled when you're trying to make a quick exit or easy entrance. Since they all seem to have a couple of 'D' rings on the back, I decided to make a quick short strap that won't get hung up on stuff as I drag it out of the car to avoid the coming zombie apocalypse. But the problem is that if it's too narrow, it's too uncomfortable to use zombies or no. So, enter the Portuguese Sinnet (also known as Solomon Bar and referenced as knot #2496 in Ashley's Book of Knots).
Step 1: The Setup:
Here's the front and back of my messenger bag. The distance between the middle of the 'D' rings is about 6.5 inches (16.5cm for those metricly inclined). I started with a length of #550 paracord 82 inches long (2.08m). I also had the following:
x. 2 12.5 inch (35cm) pieces of thin (2 mm) cord
Step 2: Begin:
Start by folding the cord in half and running it through one of the 'D' rings.
Next take a strand and run it through the opposite 'D' ring (I went 'over' the ring as you can see). Now do the same with the other.
Step 3: The First Knot:
Note: I've rotated the image to make it a little easier to reference.
Take the length on the right and bring it over the two main strands.
Now take the left strand and pass in over the strand that was just brought over and then pass it under the two main strands and through the loop that was made by the first strand.
