There are more of them, for sure. I mentally tatted 3 of them, I tested only one.
There you go.
All you need: 2 shuttles, one filled with ribbon, the other one with thread, crochet hook. Scissors. Forgot about them.
I will not make any pattern I will just "show the way" how to do it. The rest is up to you to adjust.
I worked with organza 0,5 mm wideribbon and 20 Penny polyester thread.
Why organza? because it has a fine texture. Any other ribbon for embroidery would do it.
Make a gauge for the ribbon. I made mine of 1 cm.
You will make only chains.
Take the gauge and make witht he ribbon the inner petal. Roll right 1 or 2 times the thread at the base of this petal. Remove the gauge, take the shuttle with the organza thread and start tatting the chain. Careful not to diform the measured ribbon. And I strongly advice you to snug in time. You cannot tighten this chain after some ds.
When you reach the upper part of the inner petal, you make a Catherine Wheel join, so the organza ribbon remains a continous thread trapped in the join.
Finish the chain.
You will join the 2 sides of this chain to form the ring with the thread from the roll part you did when you started the petal. secure this join and then make a slt with the ribbon. Start over.
Hope it helps. It is not so wasy to get it nice from the first try, but it works! Have fun.
