Floating Table Runner Riser

Build the base frame from the 1x2 pieces with 1-1/4" brad nails and wood glue.

Apply glue to the frame and set it on the underside of the 1x8 top, positioned well inside the top's edges so the frame won't be visible from eye level — this inset is what makes the finished piece look like it's floating. Let the glue dry fully.

Once dry, flip the assembly over and attach with 1-1/4" brad nails and wood glue for a permanent hold.
