I am open to correction here, but I think the grain direction alternates on each vebnee of the laminate, itherwise it would rather defeat the purpose of improving stability. The main reason for using laminates is that it is easier fot semiskilled factory workers to fabricate the instruments with minimum wastage.And yes, the great Spanish luthier Antonio Torres constructed just such a papier mache instrument. Some far eastern imports sound like they were constructed totally from papier mache!
