Step one: Cut the aluminum into sheets into 4×6 rectangles.
Step two: Emboss the aluminum. I placed 3 sheets in my folder at one time.
Step three: Use Mod Podge to attach the sheets to the paper mache letter. First, I wrapped the sheet around the straight edges of the letter. This was the easy part. For the curved sections, I had to trace and cut pieces to Mod Podge on.
You can glue a saw tooth hanger to the back to hang the letter, or just let it stand. You could use different embossing folders to make shapes to make it match the theme of your own room. There are hundreds of embossing folders to choose from, so it will be easy to make a monogrammed letter that is as unique as you are!
