This is the newest hand-made book I've made, and is made almost entirely of natural items, the leaf skeletons (from Thailand) the stick, (from my garden) the miniature pine cones are from the lane (before the foot & mouth problem cut off our access to lanes and footpaths) the shells are from the local beach (still accessible, thank goodness!).
The paper covering was made from white paper pulp and a small piece of black denim - cut into about 1 inch squares before being wizzed up in the goblet of my blender.
So the only unnatural item is the piece of russet coloured satin that I "borrowed" from my eldest daughter's scrap cloth box.
Oh - and the polystyrene former that allowed me to inset the oval "picture" - but you can't see that, only its effect, so we won't mention it, eh?
