hi K. - i recently had a "circus" themmed party for my 2 year old and it was a blast. i downloaded coloring book pages of circus animals, blew them up at Kinkos into posters and colored them. We hung red and white streamers from the ceiling of the basement so it looked like a "tent," and had my sister in law do easy face painting for the kids. The best part - we rented a cotton candy machine and popcorn machine from Jollyjumpers.com - the two together, including supplies, set-up, snd delivery cost about $145. For food, I had a "hot dog" bar - hot dogs in a crock pot with all the toppings - everyone loved it!!!! I would definitely do this theme again. The best part - i gave animal crackers for a give away and my house smelled like summer
