Survival Bracelets are, apparently, trendy atm, and this page will show you how to make one. The tutorial is mercifully quick and easy because the page is full of supremely irritating bells and whistles (turn your volume down!).
You can make this from pretty much any fabric, it seems. I’m going to try t-shirt yarn, but the tutorial uses para-cord. You could even add beads to girlify them.
The only translation you’ll need is: sc = UK DC. Easy!
