Step 1: Supplies and Getting started
first off, roll up the paper length-wise to the desired width of the rose blossom.
Step 2: Pinch and Roll
- from the point you pinched begin to roll the cylinder below that point to about half the remaining length of the cylinder
Step 3: The Leaf
- continue rolling the paper under the leaf all the way to the bottom
