RE: choosing lite ply...
I have heard what we use called Italian flexible ply, Italian bendable ply, Apple ply, bendable furniture ply. I guess it has a number of names depending on where and who you talk to. Last time I pick a sheet up from the hardwood dealer, it was $36.00 for a 4X8 sheet of 1/8".
I have not found this product in any of the large retail stores. I have found it in the specialty stores. If they deal in hardwoods and exotic lumber, they should have it.
