Clodfobble found these carved leaves from China.
Carving is easy, just cut away everything that doesn't look like what you want, right?
Not so fast whittler, in leaf carving you're not allowed to cut the fine spiderweb of veins, that support the leaf.
That's pretty amazing.
It would be easy with a computer controlled laser, IF all leaves were the same, but I think they're like snowflakes.
Unfortunately there's not a lot of info at the
link, like who does this and why?
So it's up to you google enhanced readers to fill in the blanks.
