I just love them! I thing they are so fun. This picture is great and I have seen many more:
I just ordered some for our carnival party we will be having in June. I am excited to play with them. I have never used one of those helium tanks you can buy, so I don't know if I should buy one of those or bring them to a party store to blow up. I'll have to check into prices. I ordered my balloons from Bake it Pretty. They have a great selection, and even some polka-dot ones.
