Made for my son's Doctor Who themed 7th birthday party. I used a huge cardboard box opened out to the shape of the 'skirt' and covered with rows of plastic circles cut from plant trays, a second box opened out for the middle section and a space hopper (covered in cling film so I could slide it out again) for the shape of the domed top. Decorations were sink plungers (of course!) and other bits of plastic and a paper cups - all covered with layer upon layer of papier mache.

I reckon it took me about 10 hours altogether so was a real labour of love but all I had to buy was the sink plungers and paint which cost about £10. It was the hit of the party and currently lives in my son's bedroom.
