You need 5-6 rectangular pieces of tissue paper to start.
Make the papers even, and fold them into an accordion shape.
Wrap pipe cleaner around the center of folded paper.
Cut the edges into a round shape.
Spread out the paper, and start lifting up each paper layer, one at a time.
Continue lifting each layer one at a time, until all of them are done.
Finished product, repeat however many times you need.
