The Domino joiner system allows me to use smaller pieces of wood or scrap to complete several of my home projects. I made a 2 panel door from 2X4s that I could join easily with the Domino, instead of more expensive 6 inch wide stock. This saved both wood and cash! Joining smaller pieces for projects also saves me time and gas in trips to the local lumber yard. The Domino, instead of more tedious mortise and tenon joints, is so simple, even my amateur skills can produce great results. Paul G., Ohio
