I presented an entry about leaves skeletons already. There you had to use particular leaves and I don’t know if they grow nearby.
Now I found another tutorial on how to make skeleton leaves where the only condition is the use of thick leaves.
I find this easier ;-)
At my next walk in the woods I think I will take a little bag with me ;-))
