First in the world eco guitar made from used - recycled paper.... All the guitar is made from paper ...also the neck and soundboard ...except the fingerboard (wood).. I make the rosetta with real leaf... I put here one video with sound from this guitar.... http://www.youtube.com/watch?v=Rum8vLvUSjM All this violins is the first i make and is a prototype. Is a full playable ...but have 1 or 2 small problem in some points. For this reason this violins is only for the exhibition and shows and not for a sold. If someone wants to buy one, would I make a new similar in appearance but not the same . All the instruments is unique. If someone wants something special, can send me and the material that wants to build a musical instrument.
