paracord braclet

After school i went over to my friends house.  his mom had bought us some para cord to make a bracelet.  We got on his computer and searched it up.  it was really easy. i got a blue bracelet and my friend got a red one.  it was basically just a bunch of square nots.  it was really simple and only took 10 minuets.  i will be taking this on my grand cannon trip.  you can un extend it and it is a bunch of rope that can save your life.  you can use diffrent lenghts of rope and make diffrent sizes
