Look at this beautiful idea using a leaf! Snake leaf
We are lucky where we live to have access to lots of natural resources such as snake skins and photos of the lovely big pythons that slide through back gardens looking for rodents and sleepy possums.
I find these box frame from Ikea ideal for displaying more fragile items like snake skins and birds nests while still inspiring creativity. The green one has a built in magnifying glass.
This little fellow is a finger puppet!
