I am about to start in on another set of room height bookshelves. My last set was about 14' long and 8' tall. I was pleased with most of the methods and materials that I used except for the walnut plywood (voids were present, some of the sheets were not straight, etc.). I of course swapped the bent sheets with my supplier but that takes time.

For this next project, I would like to see if there are any better products available. Ideally the material would be 3/4" (plywood 3/4"), void-free, 'thick' surface veneers, and be very strong. I'm thinking of Appleply quality but with a good 1/32"+ or so hardwood surface veneer (walnut, cherry, etc.) so I could lightly sand. Has anyone encountered a product that meets these requirements? Pre-finished sheets is another thing that I would consider if the quality level is there.

My alternate solution will be to buy sheets of veneer and vacuum seal it to Appleply (not attractive economically in terms of $$$+time).

Any thoughts or recommendations?
