Plaques (I bought mine at Michaels for $2.50/each)
Letters (I bought mine 4 years ago when Jacob was born at Michaels - I don't remember how much they were, though. Couldn't have been more than $1-$2/each.)
Spray paint (preferably in two different colors, so the letters POP!)
3M Adhesive Picture Hangers
Picture Hanging Brackets
As I mentioned above, I bought the letters back when I was pregnant with Jacob and had already painted them a light blue to match the color of shelves that are hung in his room (a full post with pictures of his room will come later). So, this part was already taken care of.
Jacob's proud of his letters. :)
I got different shaped plaques to add a little spunk to the letters, also.
I had to have my handy dad come hang them for me, though ... there was NO way I could have hung them on the wall and had them look this nice!
