Does anyone know of a source close to Concord that carries 4'x8' or 4'x4' sheets of 1/4" thick MDF? Home Depot used to carry it but they're down to just the 2'x'4 project panels. I need 2 pieces of 4'x4' to finish up a cabinet project. Really trying to avoid a trip to Gibsonville for such a small load. Thanks in advance!
