Step 6: Inside each circle, draw a spiral to represent the folded petals inside. The swirls don't have to be perfect. Just make sure they cover the entire circle. It's actually better if you give the swirls a bit of an angle to emphasize the petals inside. Space out the spirals too. Don't loop around too many times.
Step 7: Continue to add the spirals to the shapes at the top. The shapes closer to the top are narrower, so make the swirls thinner too. Remember that you can angle the spirals a bit to emphasize the petals. Alternate the looping from clockwise to counter-clockwise to make the roses more varied. The spirals don't have to be perfect. They're just a representation of the flower petals.
Step 8 (optional): Draw a few short lines that connect the sides of the spirals for detail on the flower petals. These lines shouldn't overlap the swirls, just connect the sides. If you've drawn your bouquet too small, you can skip this step. The roses at the bottom should have fewer lines because the tops are facing front.
Step 9: Draw a series of cloud-like shapes around the roses for filler flowers. Filler flowers are added to bouquets to compliment the main flower. These cloud-like shapes represent a flower called baby's breath that is often paired with roses. Don't make these shapes too big. Add enough to make the bouquet of flowers rounder.
Step 10: Add a few leaves around the bouquet of flowers to help fill it out more. Each leaf is made up of a couple of curved lines that come to a point. Don't overdo it with the leaves. Just add a few to fill in some gaps.
