The Tilly board is a high functionality board made out of Spruce. These Spruce boards are laminated together. The first and last layers run parallel with each other and this creates high stability to the board because of the middle board running the opposite to the first and last layer. These boards are planned to the exact thickness. The Tilly board is amazing for kitchens, furniture, ceilings, floors, walls, doors, drawers, windowsills and lots more.
