I've had to take my laptop home for some work and got tired of awkwardly carrying everything along with a lunchbox while trying to navigate through doors and my pocket for car keys.
Since I had some #paracord lying around, I looked up what kind of #knots I could use to temporarily bundle everything together.
This starts out as a simple single lashing (#ABoK 2076), then a diamond pattern lashing (ABoK 2087), and finally 3 parallel loops (ABoK1077) for a comfortable wrist handle.
