I purchased the Scrapbooking Chipboard Alphabet letters from Target's $1 section. They are currently 50 cents for a pack of 55 letters. I just found the pink ones. They have been out all summer so they may be hard to find. For the tilde that goes over the 'n' and the accents, I just cut some from the leftover chipboard. I plan to use the pink letters as the vowels.
