bought wooden letters, painted them with acrylic paint. I bent out the edges w/a needle-nosed pliers & them smashed them with a hammer! You'll kinda have to plan out how you're gonna layer all of them on before you do it so you don't end up with awkward spaces that can't be filled. The edge ones just have to be bent however you want them to fit before you glue them down. &I just used hot glue! maybe for a fraternity!
