Clover story...

Sometimes you just select some pattern, tat/knit/crochet it, get pleasure and result, and that's it. But sometimes needlework becomes a truly research... This is one of such cases.
Everything started several days ago when I was looking for some easy pattern with big rings and picots (yeah, again!) to test new threads. In fact big rings are rarely used in patterns, and I found nothing interesting. So, I tatted something square looking (motif #10):

The pattern is pretty easy:
Central ring is: R 6 - 6 - 6 - 6
All small rings are: R 3 - 2 - 2 - 2 - 2 - 3 Cl
All chains are: Ch 3 - 2 - 2 - 2 - 2 - 3
At this moment my story could be finished if my husband didn't say that this motif looks like four-leaf clover, the symbol of Luck. Shame on me, I knew nothing about it. He showed me a picture and asked whether I can tat it for him. It was a challenge!
These are my several attempts to tat it, using different threads:

The left top clover (motif #11) is the first one.
Every ring in it is: R 4 - 10 (8 first parts of knot) (8 second parts of knot) 10 - 4
My Alex didn't like it much as it is very "empty". All the other thing on photo above are my attempts to make the "full" one. Finally I tatted this one (motif #12):

It is the best one - we both liked it! It's pattern is a bit similar to the Hibiscus pattern. I will write it a bit later.
So, thank you, Alex, you give me inspiration!
