I really found this frustrating exercise. Some would say that's good.
First it was sooo small, 12" sq, and second, the first iteration was so similar to what I might have done.
I wasted a lot of time trying to reinvent the wheel, in this case leaves.
MY background was really busy so it called for a simple finish.
And as this is supposed to be 'secret' until all the versions are done........I'm not going to post a picture of the whole, just a slice.
You'll have to wait another six months+ to see the end results.
As for me...
I can move on.
