I had the idea for this from another post, but I cant for the life of me remember which one! (sorry)
I think they're gorgeous, and will look amazing in different colours and hanging from the ceiling.
They're made by rolling up a ball of newspaper, and covering in tape to keep it in shape. Poke your finger into the cupcake case and pinch into a point. Then use glue (i prefer using a hot glue gun because its quicker but i guess PVA would work fine too) to stick them around the ball.
Once the ball is covered, have a prod around to check for bare patches and pop some more in if there are. And Voila! A very pretty and quick decoration. I'm going to buy pretty patterned cases and make loads!
