This bracelet is easy to make, but also to unmake, so you can bring with you a piece of rope as if it was a beautiful bracelet.
check out my blog for more projects:http://myvirtuoushands.blogspot.com.es/
Make a loop in the middle of your rope.
Now pass one side of the rope like this...
...and then the other...
... and tight it so it looks like this. Leave that loop in the bottom to be able to put your bracelet when you finish it.
Now you just have to do the same: introduce one loop through the other that is already made...
...and tight it.
Continue doing this until you reach the long desired.
To finish the bracelet pass completely one side of the rope through the loop and tight it.
and that's all!
Now, if you want to undo the bracelet untie this last knot and just pull both sides of the rope in opposite directions.
I hope I've explained everything so you could understand it, anyway I think that the photos explain it better than anything that I could have written ^.^"
