Stencil size and PCB service

I am interested in getting stencils for my design. I see you have a few sizes for stencils, all pretty big. I assume the stencils are intended for a panel of boards. Say if I order a stencil with 37cm * 47cm, then where do I order PCB panels of that size? Your PCB service only provides single boards. Do you also ship panels that match stencil sizes you sell?
