Kumihimo - tutorial; flat braid with hearts

I thought I´d post a tutorial of a kumihimo pattern; flat 12-tread braid with heart pattern:

For about 2 bracelets (finished length 30+ cm), I used 6 x 1,20 m lengths; 5 x 1 mm cords in dark blue satin and 1 x 2mm cord in pink satin. The thicker cord might be a bit shorter if you want. Lay the threads double and place the 12 threads in the starting position as shown under.
(I will refer to the disc as a clock: 12 o´clock is on top, 3 o´clock is to the right, 6 o´clock is bottom ans 9 o´clock is left.)

This is the starting position of the threads. I mark the top with a pin to keep track. 

First take the inner right thread in the 12 o´clock position and move it down below the two threads on the left side, in the 9 o´clock position.

Take the inner left thread in the 12 o´clock position and move it down below the two threads on the right side, in the 3 o´clock position.

Move the two top threads closer, replacing the moved threads.

Now, take the inner left thread in the 6 o´clock position and move it up above the two threads on the right side, in the 3 o´clock position.

Do the same move with the inner right thread in the 6 o´clock position to the left side.

Move the two bottom threads closer, replacing the moved threads.

This completes the first sequence. You should have two threads top and bottom, and 4 threads left and right.

Take the top inner thread in the 9 o´clock position and move it down to the left side of the two bottom threads in the 6 o´clock position.

Take the lower inner thread in the 9 o´clock position and move it up to the left side of the two top threads in the 12 o´clock position.

Move the two remaining threads on the left side closer together, replacing the moved threads.

Now, it´s time to repeat with the right side. Take the upper right thread in the 3 o´clock position and move it down to the right side of the lower threads in the 6 o´clock position.

Take the lower right thread in the 3 o´clock position and move it up to the right side of the upper threads in the 12 o´clock position.

Move the two remaining threads on the right side closer together, replacing the moved threads.

This completes the whole sequence. You need to repeat the sequence 3 times to get the pink threads back in the starting position, creating 1 heart.

The braid in progress!

A while later.....

Good luck!

Ps: I would love to have the startup position (pattern) of the round 16-thread heart pattern. If anyone cares to share: Please leave a comment!
