If you need to paint your letter, do it with acrylic paint. Give several coats and let dry.

You will need to work in small sections since the Mod Podge dries so quickly. Brush some Mod Podge on a section and then begin layering on your confetti.

I made my own confetti by using a large dime size round punch and tissue paper.

Start spacing out the confetti as you get closer to the bottom of the letter. Don't forget to add some to the sides as well!

Brush on a layer of Mod Podge over the whole thing to seal it.

Hang the letter and enjoy (make multiples if you like!).
