I have a maple branch, sanded smooth that I need to finish/varnish/whatever you call it with completely natural, non man-made materials. As in even something a 14yo could cook up in a regular kitchen. It can't be manufactured at all. She can buy it premade if it's possible, but there can't be any man made materials in it.
Does that make sense?
Plus it has to bring out the naturalness of the wood and not stain it a different colour from beyond the natural one of the wood.
