I don't think I have done any with day parades that I'm aware of... but you could get like star and cloud stickers and embellishments then a sticker that says "Dreams really do come true" they have it on the Disney Scrapbooking section of your local craft store. Hope this helps!
P.S. I have an interview set up at a local scrapbooking store to help out people with this type of stuff, let me know if I helped our not! I really need a confidence booster!
