Flexible bending plywood – this is a product that is made either long grain or short grain depending on which way you need to bend it. The grain on the faces opens up like the ridges of a fan giving flexibility but lots of gaps in the faces. Flexible MDF – this is a product that is made either long grain or short grain depending on which way you need to bend it. The MDF is routed out in straight lines 4mm or 5mm apart allowing for a ridge like effect on the outside of the board. Smooth but not round, looks like it goes around in steps. Flexible paperbacked veneer – this is a 0.8mm sheet with brown paper on one side and the veneer glued to the face side. Generally long grain and can be wrapped around your finger, as it is so flexible, as long as it is the direction of the veneer.
