How to make an acorn

Hi, Newbie here. I want to model a 3d acorn. Would I do half of it and then revolve command to make it 3d? Please let me know. I don’t have a drawing right now. But I have a photo I pulled off the internet.

So, an update. I can get the basic shape in rhino, but not sure how to add the little triangles on the 'lid" of the acorn?

A good starting point would be to use the Project command to get the scales on the cap. There’s some tutorials on youtube to show you how it’s done. https://tinyurl.com/y82t74y8
