Step 4Slide Your Mirror into Place
iImage Information

In this step you will be sliding the mirror into place and sealing up any light leaks with duct tape. I found it surprisingly difficult to get the mirror all the way in the box, sand paper was a huge help. All I can say is don't break your mirror trying to do it. Remember, the mirror should face the open end of the box where the TV will be and the hole we made on the side. Ignore the hole you see in my pictures. Now that the mirror is correctly seated in the box, tape up the sides so it doesn't slide out of place. Now tape your magnifying glass over the hole you cut in the side. Compare your finished box to the one in my pictures. If you look into the open end you should be able to see right out through the magnifying glass.
