Report ready to go in Furniture 4 Posted February 10, 2017 Hello Brian, The bottom and top stretchers are mortised (& tenons) into the legs. btw, the stretchers are ship lapped into each other. I put a screw from below into the lower stretchers, but that is probably unnecessary. In fact, I am building another short version of this design as a gift and will not bother with the screw into the lower stretchers this time. Thanks for your comment.
