How do I make a cabinet with an old 6-9 pane window?

Hello Katie! This link gives you a basic idea of how you could make a cabinet quite easily using your window as a door for the cabinet. You can adjust the depth of the cabinet by the width of the boards you use. This is more of a cabinet to hang on a wall but if you have some DIY skills you can make it larger and even add feet to the bottom. This is just a basic idea for you to consider.

To piggy back off Gk's post, when I build something along those lines I use wood glue and clamps to hold in place and then small nails utilizing a nail gun. I've never had any of them com apart and since I use such small nails they are not visible either.

The triangle windows are they in good enough shape to sell? You could donate them to a habitat for humanity type of charity.

Hi Katie. You could use the flooring to make a box, Start by making a wood plank frame the same size of the window. Use wood glue and small nails to make the frame. Then attach a few more floor planks to serve as the back. Put piano hinges on the window and attach it to the box. Use a strong (E 6000) adhesive to attach a knob on the window. An unusual piece of jewelry would look great as a knob. I hope this helps you. Please consider posting this project here on Home Talk. Good luck Katie.
