How to apply pattern on curved surface?

This is going to be a little work, but is possible.

1. Create the profile or revolved shape of your earring.

2. Create the pattern object

3. Copy the pattern object to follow your profile (arranged on the cross section). You can scale and /or rotate the copies as well.

4. Use the circular array to make copies around the full 360 degrees

5. You may need to create 2 (or more) arrangements of your pattern object to get what you want.

For example, arraying copies of 1 pattern arrangement would not produce the spiral effect. So you would need to create a 2nd pattern arrangement to alternate with the 1st
