Paperbacked and 2-Ply Veneer Guide - Joe Woodworker

The factory can usually get 5 to 7 paper-backed veneers in a 10" x 10" x 50" box. Two-ply veneers ship in a larger box because it can not be rolled as tightly as a paper-backed veneer. This box is usually 14" x 14" x 50" and is considered oversized by the carriers so the shipping rates are a bit higher.
