Need help with costume
I need to inflate a costume and don’t want to purchase a ready-made one. Can anyone tell me how to do it myself? My daughter’s school is doing Willy Wonka, and I need to make Violet blow up like a blueberry. The costume part isn’t a problem — I just don’t know what sort of fan to use, and I don’t want to have cords coming from her, so it needs to be battery-powered, portable. Thanks!
