In his "Book of Knots and Ropework" Eric Fry calls this the Pineapple Knot. I started with 2 40" long lengths of paracord folded in halve and seizd together

This is a fun knot to play with. The ends can be cut flush with and hidden in the knot. You can cut the ends away from the knot and either brush the ends into a fringe or leave them alone. You can have more than one over under sequence as you start the knot or have zero over unders and go directly from one crown to the second. You can certainly use 2 colors if you desire. If you switch the direction of the crown knots you will change the direction of the turns of the knot
