The pink part is made from a plastic wallet, which I just cut up and bent around to make it stand up. The paper pieces are stuck together with PVA glue, and the ones that have plastic in them too were fixed together with simple metal rivets. Each piece has a hole through the middle, which isn't too visible on the paper piece, but you can just see it in the pink one. To make each layer, I just cut a hole into the paper, then cut spikes around the hole with scissors or a craft knife, bent the spikes around to get the shapes I wanted. The layers were then fixed together.
