Party on a Budget Tip #3: Use What You Have Chima theme. We had no lack of toys for our cake and decor! Po, my cake topper is a Happy Meal toy! Chima theme. Printed out my own birthday banner, since there were none to be bought! Baby toys & primary colors theme. I already had plenty of baby toys to choose from! Nerf theme. Target practice with disposable cups and army guys we already had. Everything on the wall is stuff we already had, except for the $1 yellow tablecloth. A little bit of spray paint and a printed out Batman logo, converted this sign from a generic, then Elmo banner to a Batman banner!
