Pattern for the beaded flower

As I told before... beads phase im my tatting.
I just made this flower and someone wanted the pattern. It is not a big deal, it is not difficult at all.
Starting element is the most common 6 petal flower done with 1 shuttle. There are some beads on it. The second round just goes around the flower and the beads. This is the part wich gives a nice shape.
I guess someone else wiser and smarter tham me has to have found this idea before, but I never saw it. If it is the case, I apologize and I will be grateful if someone can point me the author, if there is one.

The pattern is done for a 12 Anchor Freccia  thread (like the 60 DMC, if I remember it correctly).

What you need: 30 seed beads.

Wind your shuttle and put the 30 seed beads on the thread.

Take 4 seed beads and start the ring. 8ds - 8ds - 3beads from the loop and 1 from the shuttle 8 close. The fourth bead from the loop will remain at the base of the ring.
Repeat 5 times, making the joins to form the flower.
Cut thread.
Easy.

Second round: all chains. (marked red)
Begin from the join picotsof the flower.
Chain 12ds, make lock join to the thread between the 2 seed beads.
Chain 4 ds - 4ds lock join after the bead on top.
Chain 12 ds lock join at the picot from the flower.
Repeat until the round is complete.

What I noticed while playing with this pattern.
For the outer round, you shoud add not more than 4 ds at the amount of ds used as a base for the flower. My case here: 8 for the flower, 12 for the outer chain. Less ds do not bring a nice shape, more ds will make a nasty join with overlaping chains.
When you make the lock joins for the outer round, you should consider passing the thread through the picot and not bellow the picot from the flower. Result: a smoother transition. When I made the join fom the lower part of the picot, I had a knottier join and a longer part of the thread was visible. Not nice.
The nastiest part: the join where the flower was closed... Patience needed.
If you use beads bigger than 1mm -1,5 mm, you should replace the 4 - 4 sequence with something fitting to your material.
