You'll need 4 large flowers, 3 medium and 3 small. Punch holes in the middle of each flower and attached with a brad. The color doesn't mind, you won't see it anyway.
Spray with water and fold the first layer, I think it works well with the stylus, maybe you can work with a tooth pick if you don't have a stylus. I spray water between each layers before to fold the petals.
This is what it should look like when the 3 first layers are done.
I also use my fingers to help squeeze the bigger petals
After all 3 medium layers are squeezed, it should look like this. Don't forget to spray water, enough but not too much!
It is done now and the fun begins...
With the tip of the paint brush or a small dowel roll down each petals during the flower is still wet
