DIY hot air balloon are a cute and fun decoration for your next party. They can be used either outdoors hanging off branches in the garden, or indoors hanging from the ceiling or lights with string. They are perfect for a high tea themed party, a kitchen tea, or even just as a general decoration for a party with no particular theme. Treat the kids and hide little tokens in the baskets for a fun game for the little ones. Tip: try coating the balloon in a light layer of petroleum jelly to prevent the doilies from sticking when you pop the balloon.
