I’m glueing solid walnut lipping to the edges of the screen panels. The lipping will hide the edges of the MDF. There are a few options to achieve this, including glueing a band of veneer onto the edge, but this method gives the best quality finish.I coat both the walnut and MDF with glue and then hold it on using masking tape. The walnut is slightly wider than the MDF so I can plane it flush to the surface. The veneer will cover the whole surface.
