Make sure your shadowbox has a removable interior frame. You will use it to insert the LED lights between the glass panel and the mirror.
Remove the glass very carefully to avoid breaking it.
The purpose of the film over the glass is to create a two-way mirror that is transparent on one side and reflective on the other. Glass is not reflective, so you need to put a reflective film over it so that it is just slightly transparent. When the LED lights bounce back and forth between the two-way mirror and the regular mirror, you get the fascinating infinity effect. You can find the reflective film at any craft store or online. You can also use car window tint film from an auto parts store.
If you can’t find a mirror that fits your size frame, you can go to a home improvement store and get one cut for you. [9] X Research source
There are a variety of LED lights you can choose from. They can be one color, white, or multi-color. The LED strip will have black lines that indicate where you can cut it. Make sure you only cut the lights where it is indicated on the strip. If you don’t, the lights may not work when you turn them on. If you have a few extra LEDs that don’t fit inside the frame, you can wrap them around the edge of the mirror and stick them to the back. [11] X Research source
This positioning between the two mirrors will give the illusion that there are multiple rows of lights instead of just one.
Be careful when using the saw. Move it slowly so you do not cut through the frame.
