Follow Me wouldn’t really be the appropriate tool for that. I would draw a reed and make it a component, then use Move/Copy and Rotate/Copy to make an array of them.
Do you need to have the inside surface with the same reeded shape as the exterior.
FWIW, making a single reed component and copying it as I showed will have less impact on file size and performance. If that’s the only object in your model it’s probably not a big deal but if this is part of a larger project, it would be something to consider. Don’t add details that don’t contribute to the “story” you are trying to tell.
