For panels which extend further in either direction, we construct SEAMED PANELS which require the joining of two sections of surface ply over the cradling frame.  We then completely fill and sand the seam to a virtually undetectable smoothness.  The calculated price above includes a charge of $30 per seam.  WE DO NOT RECOMMEND PAINTING DIRECTLY ON SEAMED PANELS, but rather use them as a substrate for stretched canvas or linen.  Please contact us directly to discuss the many possible solutions for larger panels.';
