Is it possible to purchase melamine sheets like the kind used for
shelving in widths greater than 11 7/8"? I asked at my local HD and
Lowes, and building supply companies with no success, both bigbox
places said it was not manufactured any larger than shelving width.

Home Depot sells it in 49" x 97" sheets. Doubtless, the droids working on the
aisle where they sell shelving are completely unaware of this, but if you just
walk over to the lumber department where they keep the plywood, you shouldn't
have any trouble finding it.
