Twin Ties: First Tutorial

OK, so here is a pattern that I, an expert, can make in 5 minutes 34 seconds, and I as a beginner, took 5 hours to make. Have fun!
************************************************************************************
First, cut six threads, 24 in. long/each, 3 of each color. Tie them together in an overhand knot, and separate them into 2 groups.

Now, you will make your first knot. (You only need single right & left knots for this one, thank goodness.) So, make a single right knot with the group on the right, in this case, blue, LEAVING IT ON THE RIGHT.

Next, make a single left knot with the green, leaving it ON THE LEFT.

Repeat these steps until perfect length. Seen below is what yours [probably won't] look like after about 11 sets.

When done, an expert's would look like the picture shown below.
