Not sure who this is addressed to re: shipping. be sure to allow overage for cutting, off-color pieces and slight damage. If your room needs 60 sq ft to cover the floor area (only?) then order 65-68. They may also be packed in sheets of ten, which then should go 70. I've used variations of this in several jobs, there are always a cpl odd pieces in color; you'll be glad you have a few extra sheets to work with and pull from.
