You will need : Double sided paper, 3 flower punches in different sizes, something to poke a hole with, a mini mister filled with water and planty of spare water to hand! I worked on a non stick craft sheet.
The original tutorial said to use 4 large and 3 medium and 3 small flowers. I did that at first but then reduced them to 3 large and 2 each of the medium and small so it is up to you really as to how many layers you use. I just found it gave me the finish I was happy with with less bulk.
Punch out your desired quantity
Poke a hole though all of them and fasten together with a small brad.
Then spray liberally with water; don't be shy with the water! Then start to fold everything inwards covering the brad until you end up with a sodden lump that looks something like this!
Then begin to open the petals out one by one shaping them as you do. You will need to be a bit careful as the paper will be fairly fragile.
The end result will be something like this:
