Jellyfish Costume - such a creative use of some colourful ribbon and an umbrella! Such an easy and cheap costume for a costume party, Halloween party or fancy dress event! Maybe it could be cool for an enchantment under the sea prom ball party!
These Lego masks use a cardboard frame wrapped in yellow papers, and they also have translucent eye-holes, so you don't have to worry about bumping into things. They are very light but also very sturdy and impact resistant - perfect for a party!
