Take 3-4 tissues or depending on how dense you want the flower to be and trace circles.
Cut the circles; make sure to hold all the layers of the tissue. You can use paper clips to hold them together. Keep the circles together and staple in the centre.
Start making petals by separating the top most circle of the bunch and crumple it upward from the centre. Repeat with each circle and keep gathering the crumpled circles upward.
Once you are done gathering them, open the layers gently to give a more fuller and realistic look.
And that’s it; you have beautiful flowers ready to decorate the way you wish.
