i added most of the mushrooms from my previous projects
you can find them under my profile

as you can see on the picture i put one mushroom next to the other and adjust the size
create an outline of the small one 
which i edit with edit node to get lines here which i also cut

as you can see here, i took a leftover piece and adapted all the figures to make good use of the leftover wood

i painted them all differently but also the back with a different color
so every time you redistribute them you get new color combinations :)
