I build a lot of bunk beds and like to use the kreg to secure the top and bottom bunk. However I don't like the look of the kreg plug without finishing it. To solve this problem I came up with a "Decorative" removable plug. I mitered a piece of 2x2 stock and glued it to the plug. I had to sand off some of the plug to get it to fit right. Now the plugs have a stylist look to them and hides the pocket holes well. The pics should be self-explanatory.
They are to secure the top and lower bunk together. Mine break down into two separate beds. What you are looking at is the bottom of the top bunk.
There are no joints. Only the pocket holes from the Kreg.
