How fun is this tutorial from All Things Mamma?? You can get cupcake wrappers from Michaels for pretty cheap, and there are so many fun ways to revamp this idea it's almost mind boggling! Almost... ;)
First, take a piece of cardboard and using a pencil draw the number or letter you’d like to use. Next, using an Exacto knife or scissors, cut out your number or letter.
Take cupcake wrappers (Meri Meri Owl & Daisy Bake Cups, Set of 48) and gather them together at the bottom, like in the form of a flower. Use a dot of hot glue and glue it onto the cardboard. Hold for a few seconds to hold in place.
Work in small sections around your cardboard so that the glue has time to harden a firm up.
After you’ve filled the entire space, use tulle or ribbon and glue onto the back of your number and tie a bow and hang up! That’s it!
